Whole bunch of changes: Added some more settings-related stuff and some calls
from plugin into BitlBee (where we *can* actually do return values). Also,
adding what I have so far for the Python counterpart, I suppose it makes sense
to have it in the source tree as well - though the naming/layout/etc is
completely made up.
Also, writing the commit message as if Git were a normal version control
system because screw arbitrary poorly documented "rules" on how commit
messages should be written in the world's most "special" VCS.
