This is the first commit in a series of commits
which improve the readability of some of the code
and add tests.

File: base64.js
Tests Added: True
Changes:
- Improved indentation
- Fixed JSHint errors
- Moved loop variables to be declared in the loop for better readability
  (N.B. Javascript does not have block scoping, so the variables are
  still technically available outside the loop -- it just makes the code
  clearer to place them inside the loop, since they are only used there)

Previously, tight auth was supported without any support for tunnels,
even the no-op tunnel.  No, the no-op tunnel type is supported.

Previously, if you did not specify a tests file,
you had to be in the 'tests' directory for the
"run all tests" functionality to work.  Now it
will work in any directory.

Previously, there would be a case where if your tests took
too long to run, the casper test runner would only report
on certain tests.  This has been fixed.

Now, 'error' events from the test runner are output to stderr.
Additionally, when debug is enabled, debug output is logged to
stderr instead of stdout (as was the case previously).

Now, the phrase `requires test modules: ` may be place in a comment
in a file to require modules local to the test directory, similarly
to the way the `require local modules: ` line may be used to inject
files in the 'include' directory.  This is useful for when common
fakes need to be injected into a test.

When using the '-g' option with run_from_console.js, you can
now pass the '-o' option to automatically open the generated
HTML file in your default browser.  This relies on the 'open'
NPM module.

Better parsing of query string variables

Previously, Util.getPosition didn't deal with scrolling
particularly well.  This fixes that by calculating the
scroll offset when dealing with getting mouse positions.

the fix.  Credit to Brian Huismanfor the initial code.

Closes #295
Relevant to #258

Fix keyboard handling for IE10 (issue #352)
* Keyboard events in IE10 do not provide any useful information on the properties 'which', 'char' or 'charCode'. Instead, it seems to store the char code in the keyCode property.

* The on-screen keyboard not closing when pressing Enter is more important than not having textsuggestions etc.

* This code works in Firefox on Android and on Chrome and Safari on iOS.
* It does not work in Chrome on Android, the enter key is labled "Go" and closes the on screen keyboard when pressed.

Change type of keyboardinput to password to make sure that you can write parenthesis on iOS devices.

Improved websocket binary support detection

* On slow servers where the button-images can be slowly loaded it can be useful to see some relevant text instead of "Submit query" on every button.

Fix altgr firefox

Apparently Firefox on Linux changed the value of navigator.appVersion,
causing our OS detection (used to determine how to interpret different
modifier keys) to fail.

Use navigator.platform instead, which should be more stable.

Previously we identified keys in keyboard events by the 'key' property
if it was set, and 'keyCode' otherwise.

This turns out to be problematic as Firefox no longer leaves 'key'
undefined (so we fall back to using 'keyCode'), but instead sets 'key'
to 'MozPrintableKey' for all printable keys.

This meant that when (printable) keys are released, we can't match it
against the corresponding keydown event, and instead just send a keyup
event for the last keydown received.

Now, if both 'key' and 'keyCode' are set, use the concatenation of both.
Otherwise prefer 'keyCode', as that is at least unique for every key.

This should let us release the right keys on keyup events.

A facke connection to 'wss://localhost:17523' (randomly chosen) to detect
the WebSocket binary support is not the best solution.
First of all, check of prototype has the property 'binaryType'. If not,
perform a dummy connection to 'wss://.' instead of 'wss://localhost:17523'.

This patch was inspired by the discussion and implementation of Modernizr:
https://github.com/Modernizr/Modernizr/issues/370
https://github.com/Modernizr/Modernizr/blob/master/feature-detects/websockets/binary.js

WebSocket protocols are now configurable

Use wss when creating localhost connection to detect binary support (closes #242)

Add support for connecting to TightVNC servers

Remove the connection timeouts
