Rocks, Ice cubes, and Icicles should push buttons, and activate switches.

relevant to #1354

This type of mechanic would offer a great increase in dynamic to gameplay. There may also be other objects that should interact with buttons. Also, it just makes sense. Things that have weight should be able to crush things that Tux normally would.

Rocks do already push buttons.

[Alasdairbugs]
