Added gitignore… hopefully I don't regret it
Added a lastMessage property to the CardMatchingGame - mainly committing to make sure git isn't broken.
Update message when you match a card
Add number of points
Added a label to display the message
Added message for flipping card penalty
Fixed some bugs, now the card matching works properly.

Still need to figure out how to set the background image for a button only in the "normal", non selected state.
Commit these for now, before adding to git ignore again
Unset the background image if it's set
Stop tracking user interface state, we don't need it!
