v0.05 - 2 More Rows & A Color Bag

This one's super fun and actually makes hard mode playable.

I added two rows to the board, fixed color generation (it's now got it's own bag system so every bag will have an equal amount of each color), I removed pencils with solid bits (might be temporary might keep it this way), and fixed the most annoying bug of pieces not merging properly when dying, as well as some other minor bug fixes.
