- Added support for using kdesu instead of gksu where it makes sense.
- Improved code used to sanitize network keys used with wpa_passphrase.
- Removed some unused functions and imports.
- Cleaned up some comments/docstrings.
Experimental:
- Split gui.py into gui.py and netentry.py. netentry is imported by gui.py to make use of NetworkEntry and its subclasses.
- Reorganzed how dbus and the language dict are used in wicd.py and gui.py.
