Fixed a bug where iron bombs would not stop exploding due to slow performance. I have not tested this on a high performance machine yet.
Moved the popped checking into the base bubble. You have to check if popped is false then set it to true if you are calling just the pop method rather than collision.
Added a wall function that returns what side a rect is facing towards the wall.
Fixed a bug with pop checking. Also the pop checking works on higher performance as well.
Merge branch 'develop' of https://github.com/despondentdonkey/bpm into donkey
Drastically improved collision detection.
