Vermin module and colonies plugin

This is the start of the vermin module.  Right now it just gets a list
of the positions at which vermin are created (spawn points).  Most
spawn points are invisible and transient, but colonies (ant hills and
such) are permanent and visible.  The address of the spawn points vector
is only provided for Linux 0.31.25

The colonies plugin uses the vermin module to list the location and
species of colonies, and can either wipe them all out or turn them all
into honey bee colonies.
