experimental branch:

- Enhance dbus manager to handle settings up mainloops, etc.
- Early work on getting wicd-client to recover from a daemon crash.
- Simply how the the scripts editor gets launched.
- Remove unneeded cleanup code from netentry.py
- More ralink legacy work.
- Run scans in a thread, this should make the UI more responsive while a scan is going on.  Rework the UI code to never expect a scan to be blocking.
- Don't require the daemon to be restarted when we switch backends, just try to prevent any calls to the backend until the switch is made.
