Gem Hunter 0.6.0 release

I reworked the piece of code that handles block removal when 3 or more blocks of the same type are lined up in a row. I did a little testing, and it seems to work correctly now. The score might still have some issues, I'm not sure. I'm planning on implementing a combo system sometime in the future that rewards you more points each time blocks drop and you keep a chain going.

Also I should spice the game up at some point when the mechanics are done to make it more exciting! :P
