Improved use of screen real estate

Display the desktop name in the document title

  button group instead of centered.
* On low resolution devices the padding towards the edges of the screen of
  the left and right button groups are now removed.
* Since the status_bar was merged into the control-bar the actual status_bar
  element became redundant and was therefor removed.
* Improved the style of the control-bar when there is an error or a warning.
* Implemented a fix so that vnc_auto.html works as intended with the improved
  screen real estate patch.

Also added a popup with the status text.

Re-fix pull req #245:

* Must declare port variable.

* Must look for https first, then http.

Detect port properly in vnc_auto.html when used on port 80 or 443.

Because apparently it is simple enough for me to forget to include in the previous commit.

Correctly identifies the use of http/https and forces the value of port to 80 and 443
respectively, as in this situation window.location.port is blank.

This is patch includes the same changes as made in vnc_auto.html

Also, in COPYRECT, set FBU.bytes to the number we know we will need.

Set FBU.bytes to 1 in encHandlers.COPYRECT

FBU.bytes must be set before return false to indicate that the FBU
header has been read. If not set then "if (FBU.bytes == 0) { ..}"
in framebufferUpdate will be entered and the copyrect header will
be interpreted as a new FBU leading to a "unsupported encoding"
disconnect error.

Also, update nova-novncproxy to import websockify instead of wsproxy.

Browsers (such as Chrome) don't report port numbers in window.location.port when
used on standard ports such as 80 and 443. This causes vnc_auto.html to not
automatically find the port as it should.

This simple change checks if window.location.port is blank, and sets port as
appropriate from the name of the protocol in use.

Import cfg from oslo in nova-novncproxy

Upstram OpenStack Nova package has moved the config engine into a
separate package. Mirror that change in the novnc script.

Minimize differences between vnc.html and vnc_auto.html

* UTF-8 charset defintition.

* Define IE=edge for X-UA-Compatible.

* Add Apple iOS Safari settings.

names="apple-mobile-web-app-status-bar-style"

should be:

name="apple-mobile-web-app-status-bar-style"

Tweak order/whitespace/style to match vnc.html more closely.

Consistent Unix line endings

Pressing an holding a mouse button and then moving the mouse out of the
canvas before releasing meant that onmouseup was never triggered.

Ctrl+'-' won't work on a US keyboad with the latest Firefox.

Firefox 17 generates 173 as the keycode for the minus key.

Changed the config module which includes CONF

currently CONF was attempted of being imported from nova config.py
rather than openstack/common/cfg.py. this commit fixes that.
