* Completely reworked the gui/tray system. gui.py and edgy/dapper/tray.py are now all run from the same wicd.py file.

* Added a connection_lost_counter to prevent the wicd frontend from trying to automatically reconnect too quickly if signal strength is briefly lost.
* Added some code to hopefully fix some of the dbus-related encoding problems caused by essids with weird characters.  (Might still need work).
* The tray/gui will now show up in the process manager under the name wicd (along with the wicd icon), instead of just python.
* Added a GetCurrentInterface() method to the daemon that will eventually be used in the VPN plugin.
* Fixed a possible crash caused by signal strength not being returned correctly.
* Split the Wired Profile Chooser from the appGui class, so they are now called separately within wicd.py.  When the profile chooser is called from the daemon, it sets a flag as well as sending a dbus signal, so the chooser will still launch if the wicd frontend isn't running yet.
* Added some docstrings, comments, etc.  Probably a few other small changes I'm forgetting.
