more changes incoming from Dalroi @ Raven
not checking in yet, need to have a first scan. attaching patch

<Dalroi> I've had to do some small stuff in GTK again. We needed flags
increasing to 16, and auto-include the 3 hardwired ones for easy/medium/hard. 
Nothing much, mainly changing hardwired '8's to MAX_FLAGS etc.

Dalroi: I edited out a couple of things. I temporarily nuked the version
checking, so deleted that from the diff. Also removed "gen" from the project for
compile-sake.

Dalroi: you may want to put a game-specific check around the 3 hardwired
easy/medium/hard flags I did. We used those in EF1, SOF1, SOF2, JK2, they're
originally quake/id stuff, but not everyone uses them. Especially mod people
making just DM maps.

Dalroi: You may also want to just delete the original part of the header with
EntCheck1 etc in it. I changed the #defines to an enum, but just REM'd the
original one. enum meant I could use calc'd values, and not have to push all
numbers up by 4
