Title: New buttons and stars

Adds new buttons for the next level, and restart level.

Also adds stars so that the score card now makes sense. Stars are awarded as follows:
* 1 if you complete the level in less than double the par time
* 1 if you complete the level on par time (or better)
* 1 if you complete the level with the number of clones for par (or better)
