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)

''' edgy - implements a tray icon
|
|
|
|
Creates and updates the tray icon on systems with pygtk above a certain version
|
|
Also calls the wired profile chooser when needed and attempts to auto
|
|
reconnect when needed
|
|
