Fixed bug involving heroes selling their loot.

Many bugs fixed. Most crashes should be resolved.
Heroes are far more diligent, and spend much less time wandering.
Only known bug left is units switching to rapidly attacking.

Heroes getting stuck on most activities in a loop should no longer be an issue.
Healers should no longer crash the game randomly. Most crashes should be gone now.

Fixed a bug caused by missing expressions.

Units should no longer be attacking at really fast speeds.
