Added a "Connecting..." dialog to tray icon in experimental branch
Possibly fixed issue where GUI statusbar would still show up as connected when ethernet cable was unplugged.
Changed the way wired profile chooser gets launched (now uses a dbus signal)
Fixed bug where launching gui.py through the tray sometimes left a zombie (uses a dbus signal)
Added a bunch of docstrings and changed formatting to follow python conventions
Added support for displaying signal strength in dBm instead of a percentage
Added some print statements during the ad-hoc connection process
Started work on a way to autoconnect to a hidden network (not done or working yet)
By splitting the common tasks performed by the networking module out
into a separate set of classes, it is possible to reduce code
duplication and improve the structure of the networking module.
The wnettools module now performs _almost_ all the actual commands that
control the network interfaces, splitting it from the actual connection
logic contained in the networking module. Splitting these two tasks also
allows for tool changes to be made in a central location, rather than
spread throughout the networking.py file.
