Added yapsy plugin code.
removing yapsy -- not really useful
Basic plugins framework, gui<->bot coupling cleanup, more..
ADDED: Basic plugins framework -- plugins to be added in the 'plugins' folder
       ..nothing works with this yet, it's just the module loading, etc.
ADDED: change so that when it's on my system, it uses me as master by default
FIXED: cleaned up the gui<->bot coupling.  No more error messages on exit
FIXED: GUI now allows the bot to initiate the exit on ctrl-c.
pathfinding now uses much less memory per node.
Merge branch 'master' of github.com:jpmarno/TwistedBot
