- added a Boom (strict) compatibility mode.

- Restored some original Doom behavior that received complaints from users:
* reactivated the old sliding against diagonal walls code and compatibility optioned it with COMPATF_WALLRUN.
* re-added the original hitscan checking code using a cross-section of the actor instead of the bounding box, compatibility optioned with COMPATF_HITSCAN.
