Fixes and improves doAssaultMemory (#387)

Fixes doAssaultMemory.  Bad sorting caused units to continiously forget group positions (and hence not clear them)

Improves doAssaultMemory by adding an exit condition, and requiring the AI not to be suppressed when attempting to clear through buildings in a more organized fashion.
