Another random creature creation script.

Background:
I originally made this script for my own use (which is why it is not very polished, and overall poorly written from a coders perspective), but with the downtime at the start of the new release (DFHack being updated, bugs being squashed) I decided that now was an ok time to get it a least somewhat usable by others.

Differences to others:
What makes this random creature script different is that it assembles creatures from a group of templates that the user can dynamically add or subtract from.
