Adds the CardFactory class, which generates cards on the fly.

An associated default.png has been added to be used as a background.
Additionally, a test has been added. However, due to the difficulty of
automating the check for whether the generated card image is "acceptable,"
The test outputs 3 pngs into a tests folder under PlanningPoker for the
developer to view. The .gitignore has been updated to ignore this test
folder.

More thought will be put into the holy grail of cards, the "400 of
Diamonds"
Puts the number of the card in the middle with big Font. Sigh......
Modifies the DeckVotingPanel to use CardFactory exclusively. Due to the nature of CardFactory, it may be better to check for a resource, then if it doesn't exist use CardFactory
Adds test callled GenerationSpeedTest, which is mainly for demostration purposes
Fixed issue where cards with more than 5 digits were not displayed properly. Also Fixed codepro stuff
