limits on placing towers in relation to creeps

At the very least it should not be possible to place a tower directly onto a creep.

Extending the limit out a bit could perhaps make for some interesting gameplay, but there would need to be more visual cues to clarify why a certain tower cannot be placed.

Hmm; right now it is still possible to place a tower in the same tile that a creep is currently occupying. The current effect is that it is ignored for collision purposes.
