Second committ
Merge branch 'master' of https://github.com/JonathanLifschutz/Poker.git
Committing 3 things:

i)		Slightly improved GUI (still needs lots more work)
ii)		Images of individual poker cards to be used by GUI
iii)	A fork of (in theory) simplified existing classes with tests

Going to work on Evaluator class (which is where I've rerouted game
logic away from Hand and PlayingCard classes) now...
