- Fixed some locking issues. Either lock, or don't (if you don't have to). Only locking access half of the time won't work reliably.
- Had to adapt test helpers that use the "old" IRegionModule. TerrainModule isn't one anymore.
- Change several classes to use the new plugin for handling of region-modules
(NOTE: No regionmodule is using this yet)
- Add necessary prebuild parts (don't forget to runprebuild)
Attention: Work in progress. This shouldn't break anything, but you never know...
