more cleaning up. added a way to dynamically reload data via 'reload(module)' command.  it's klunky for now.  pressing 'p' in game will reload 'gamedata.py'. For now, I can't seem to get the module to reload unless I simply put 'import gamedata' at the top.  Means I have to prepend gamedata. in front of all the variables.  If I do 'from gamedata import *', I get a namespace error.
