Monster API clones from Entity API, read more

This is my solution for handling inheritance via lua. The Entity class is
only a base class, so the entity API is designed to be copied from, rather
than used directly.

linit.c: It should be noted that the Entity API must always be placed
before the utilizing child APIs. I don't know about how lua handles things
internally, but I'm assuming that this is the case.

There's no real meat in the API code yet, since that's just busy-work.
Right now I feel beter about writing the connective tissue. This case
could aslo extend to the waypoint and monster APIs.

The waypoint system had some API and class methods removed for brevity.
