Broadway uses noVNC keyboard/input handling. Link to it.

Fixed minor typo in util/launch.sh informational output (s/to to/to/)

s/to to/to/

Including HyBi-07 support and refactor of send/recv.

- Add conf_defaults which accepts an array of configuration
  attributes.
- Split out user configuration defaults from the actual configuration
  object.
- Add mode field and enforce read-only, write-once, read-write modes.

API changes:
    - include/canvas.js renamed to include/display.js
    - Display.rescale() method removed from API. Use Display.set_scale() instead.
    - Make logo configuration attribute of Display and display it when
      clear() is called if it is set.

API deprecations:
    - use RFB onUpdateState instead of updateState.
    - use RFB onClipboard instead of clipboardReceive.

See https://github.com/kanaka/noVNC/wiki/ModuleAPI for detailed noVNC
modules and API description.

Expand and normalize the event/callback interfaces. Standize on
"onEventName" form for callbacks.

    Callback Renames:
        - RFB updateState -> onUpdateState
        - RFB clipboardReceive -> onClipboard
        - Keyboard keyPress -> onKeyPress
        - Mouse mouseButton -> onMouseButton
        - Mouse mouseMove -> onMouseMove

    Callback Additions:
        - RFB onPasswordRequired
        - RFB onBell
        - RFB onFBUReceive
        - RFB onFBUComplete

Other:
- Add array type support to Util.conf_default()
- Removed a bunch of routines from the Display API that were just used
  internally and not actually by noVNC: flush, setFillColor,
  imageDataGet, imageDataCreate, rgbxImageData, rgbxImageFill,
  cmapImageData, cmapImageFill.
- More keyboard/mouse logging when debug turned on.
- Some JSLinting

Pull from websockify a339a4856.

Still buggy so not yet activated in the UI, but the hooks are at least
here.

Separate the links from each other so it's obvious where the links
are.

github changed something about relative links.

Derived classes will almost certainly want to make use of the raw
info.

Issue #21 - non-US key handling.

Issue #21 - non-US keyboard layouts.

The code section for tab, backspace and enter was commented out for
testing but got checked in that way. Fix that.

Requested by Alexander Larsson at Red Hat to allow incorporation of
solution into HTML5 gtk 3.0 backend.

Issue #21 - non-US keyboard layouts.

Only identify some keys as special during the keyDown event so that
when using non-US keyboards the values don't overlap with the values
for normal keys.

Some keys have to still be identified in both keyDown and keyPress
since they generate both: backspace and enter for Firefox and Opera,
tab for Opera.

Also clarify usage statement with legend height adjustment.

Remove console.log in arrays.js so that it works in firefox without
firebug.

This is part of addressing issue #21 - non-US keyboard layouts.

There are several challenges when dealing with keyboard events:
  - The meaning and use of keyCode, charCode and which depends on
    both the browser and the event type (keyDown/Up vs keyPress).
  - We cannot automatically determine the keyboard layout
  - The keyDown and keyUp events have a keyCode value that has not
    been translated by modifier keys.
  - The keyPress event has a translated (for layout and modifiers)
    character code but the attribute containing it differs. keyCode
    contains the translated value in WebKit (Chrome/Safari), Opera
    11 and IE9. charCode contains the value in WebKit and Firefox.
    The which attribute contains the value on WebKit, Firefox and
    Opera 11.
  - The keyDown/Up keyCode value indicates (sort of) the physical
    key was pressed but only for standard US layout. On a US
    keyboard, the '-' and '_' characters are on the same key and
    generate a keyCode value of 189. But on an AZERTY keyboard even
    though they are different physical keys they both still
    generate a keyCode of 189!
  - To prevent a key event from propagating to the browser and
    causing unwanted default actions (such as closing a tab,
    opening a menu, shifting focus, etc) we must suppress this
    event in both keyDown and keyPress because not all key strokes
    generate on a keyPress event. Also, in WebKit and IE9
    suppressing the keyDown prevents a keyPress but other browsers
    still generated a keyPress even if keyDown is suppressed.

For safe key events, we wait until the keyPress event before
reporting a key down event. For unsafe key events, we report a key
down event when the keyDown event fires and we suppress any further
actions (including keyPress).

In order to report a key up event that matches what we reported
for the key down event, we keep a list of keys that are currently
down. When the keyDown event happens, we add the key event to the
list. If it is a safe key event, then we update the which attribute
in the most recent item on the list when we received a keyPress
event (keyPress should immediately follow keyDown). When we
received a keyUp event we search for the event on the list with
a matching keyCode and we report the character code using the value
in the 'which' attribute that was stored with that key.

For character codes above 255 we use a character code to keysym lookup
table. This is generated using the util/u2x11 script contributed by
Colin Dean (xvpsource.org).

API change: for intergrators that explicitly include the Javascript
files (that do not use include/vnc.js)js, include/input.js is a new
file that must also be included.

The mouse and keyboard handling could be useful on its own so split it
out into a Keyboard and Mouse class in include/input.js.

This refactoring is preparation to deal with issue #21 - non-US
keyboard layouts.

Fix mouse button mapping in IE9. All browsers have converged on
a standard left=0, middle=1, right=2 ... all except IE that is.

Add html5 doctype to tests.

In vnc_perf test, use do_test instead of start for function name since
start is a keyword in IE.

In error about Flash give a link to Adobe's download page.

Current timeout is 2 seconds for connect timeout. Use 5 seconds if
web-socket-js (Flash WebSockets emulator) is being used. On Windows XP
with Flash 10.2.152.26, connecting seems to take quite a bit longer
than it probably should. This should make it work more consistently.

Syncs with same change to websockify (7534574a2f).

Primary change is removal of FABridge interface.

Seems to improve overall latency by perhaps 10%. Also, the slowdown
over time in Opera is about half as bad (but still there).

This allows tests to work on the github pages site.
