- Added damage factors that allows to make monsters more or less resistant

to specific damage types.
- Changed Dehacked parser to use the DECORATE symbol tables for code pointers
  instead of creating its own ones.
- Removed the HandleNoSector hack and changed A_Look so that it uses the sector's
  sound target for actors with MF_NOSECTOR regardless of compatibility settings.
- Moved initialization of weapon slots after the actor initialization.
  With default weapons exported to DECORATE it can't be done earlier.
- Converted Doom weapons to DECORATE.
- Changed backpack definition so that Doom's backpack is no longer the base
  class that implements its functionality. Now there is an abstract base class
  all backpack-like items derive from. Also moved the actual definition of Doom's
  backpack to DECORATE.
