Cleaned up formatting in gui.py. Made glade template for preferences dialog and rewrote gui.py to use it instead of creating it explictly in the code. Fixed a bunch indentation/whitespace problems. Cleaned up a ton of formatting in daemon.py Fixed a wired autoconnect bug. Rewrote part of the connection monitoring code, further minimizing the number of external program calls, as well as number of dbus calls. Added StatusInformation methods to daemon.py, to allow external apps to poll for the current connection status without making several dbus calls. Fixed bad function call to GetDBMSignalStrength in daemon.py.
