Issue #4 - Porting resize (micro/macro) systems.

* Instead of "playerscale" we are using pre-existing variable
 "size_multiplier" but we move it to /mob/living
* Added basic mechanics of size changing.
* Mousetraps snap small people even if they have shoes.
* Big people can walk over small people, or stomp them, or capture them
 in foot slot.
* Ported holder for micros, making small people scoopable.
* Tied held micros in with the vore code so they are edible.
* Ported size-altering reagents and recipies.
* Ported size gun along with associated sprites and sounds.
