Testing
Merge branch 'Royse' of https://github.com/derekroyse/monopoly into Royse
First (failed) attempts atadding a roll button, dice result + player cash display, and inter-turn spaces.
Implemented a roll dialog box. Not perfect yet, but it displays the current player, their cash, what they rolled, and allows the user to end their turn.
Added a JLabel to the roll window for messages
Tax spaces and free parking

I added functions to deduct and add money to the player, and what
happens when you land on the tax spaces and started a big else if
structure for spaces like it. Once the messages label is working
properly we should be able to just uncomment that line where the text
is set. I also coded Free parking because it was super easy and needed
to be done.
