- VC++ doesn't seem to like the TArray serializer so I added a workaround

to be able to save the 3dMidtex attachment info.
- Fixed: The TArray serializer needs to be declared as a friend of TArray
  in order to be able to access its fields.
- Since there are no backwards compatibility issues due to savegame version
  bumping I closed all gaps in the level flag set.
- Bumped min. Savegame version and Netgame version for 3dMidtex related
  changes.
- Changed Jump and Crouch DMFlags into 3-way switches:
  0: map default, 1: off, 2: on. Since I needed new bits the rest of
  the DMFlag bit values had to be changed as a result.
- fixed: PTR_SlideTraverse didn't check ML_BLOCKMONSTERS for sliding
  actors without MF3_NOBLOCKMONST.
- Added MAPINFO commands 'checkswitchrange' and 'nocheckswitchrange'
  that can enable or disable switch range checking globally per map.
- Changed ML_3DMIDTEX to force ML_CHECKSWITCHRANGE.
- Added a ML_CHECKSWITCHRANGE flag which allows checking whether the 
  player can actually reach the switch he wants to use.
- Made DActiveButton::EWhere global so that I can use it outside thr
  DActiveButton class.

March 17, 2008 (Changes by Graf Zahl)
- Changed P_LineOpening to pass its result in a struct instead of global
  variables.
- Added Eternity's 3DMIDTEX feature (no Eternity code used though.)
  It should be feature complete with the exception of the ML_BLOCKMONSTERS
  flag handling. That particular part of Eternity's implementation is
  sub-optimal because it hijacks an existing flag and doesn't seem to make
  much sense to me. Maybe I'll implement it as a separate flag later.
