LINDA, Stage 1

This commit ports the base system of LINDA from TG. This version of linda
is the original version, with none of -tg-'s fixes, rewrites, or other
such improvements attached.

The mob ignite system has been 100% removed, as LINDA does not support
this normally. It may be added back in when the improvements and refactors
to LINDA have been ported.
