Separate character and weapon sprites

[danielduner]

The character sprite currently contains an image of a weapon. It would be good to separate out the weapons, to make it possible to switch between different weapons and tools.

This is needed for #736, #265, #41 and #118.
Also see the forum post about it: http://forum.catacombsnatch.net/thread-153.html

Also hats. But that should be a separate issue.
