- Made several DECORATE errors which do not involve parsing non-fatal.

Browse source 
- Added a static error counter to FScriptPosition class.
- Changed initialization of actor class type properties: fuglyname is gone as
  is the postprocessing in FinishThingdef. Instead an empty placeholder class
  is now created when a class is first referenced and this placeholder is later
  filled in. 
- Added option to replace backslash with '^' in state frame definitions because
  the backslash is just causing too many problems because it's also an escape
  character.
