- The player race enum has been expanded so that it can also be used as monster race; it's not yet used as such though.
- Additional races Vahnatai, Plant, and Bird added.
- Alter the terrain special flags so that they can be used as signed shorts in the few cases that require it, and changed dangerous terrain to combine the curse/bless and slow/haste cases.
- Fixed an unnoticed error which would have probably prevented monsters from being affected by conveyors.
- Refined the dangerous terrain special ability with more messages and also handling all cases except weapon poison.
