Make contact names editable in the GUI, but sadly quite hacky as yet :

It won't update merely because the user changes the name, users must actually
press enter or maybe click somewhere.  Ideally, some destroy event should
triger the update or something.

I suppose c.save() should not be called at some point, but presumably
not just because the user types by accedent, probably use whatever triger
changes contact.name.

I have not yet found any nice way to update the sidebar because actually
mainUI builds it, probably needs refactoring.

All these issues could be simplified by using a dialog, but thus far pond
avoids them, and I disliket hem myself.
Just slightly better rename for the GUI, still sucks.
Check to make sure another contact doesn't have the same name.

Detect tor port even in developer mode so that PANDA can run properly under TBB.  There was an issue because PANDA runs over tor even in developer mode, but TBB uses port 9150 rather than the default tor port 9050.

Allow tor to be used by PANDA when running in developer mode

Oops
