November issues

Addresses #12 and #13 , and provides a stopgap for #9.  Depends on https://github.com/opentechinstitute/commotion-linux-py/commit/d148f590609d937b7f91323bfa50a8c8e04c7583 
To test:
1.  Install on a test machine with two wireless adapters, one which supports both ad-hoc mode and ibss-rsn (via nl80211 support), and one which does not.  Ensure that both adapters are active.  Attempt to connect to a Commotion mesh using the applet, preferably several times.  The code passes this test as long as the wireless adapter that does not support ad-hoc mode and ibss-rsn is NEVER invoked by Commotion.  (Check syslog to confirm).  
2.  Edit a profile using the new built-in editor in the applet menu.  Optimally, you should see a very minimalist text editor with nothing but a Save button; however, the code still passes this test if you get a gedit window instead (the fallback).  You should be able to save the profile without encountering any permissions errors.
