Added animations to Stage & cleaned up CombatPage to use the Stage

Decreased the animation time for the popping. Looks a lot better.
Now the bacterias take an arc from the enemy to the player.
Merge pull request #35 from rhololkeolke/master

Changed Bacteria Trajectories
Refactored all of the collision checking into separate functions so that the main loop
reads better. However, I would still like to figure out a better way of encapsulating the interactions
between objects.
