of type MiscPatch with the same name. - Added UDMF line trigger types MonsterUse and MonsterPush. - Separated skill and class filter bits from FMapThing::flags so that UDMF can define up to 16 of each. Also separated easy/baby and hard/nightmare and changed default MAPINFO definitions. - Changed: Crosshair drawing uses the current player class's default health instead of 100 to calculate the color for the crosshair. - Added SECF_NOFALLINGDAMAGE flag plus Sector_ChangeFlags to set it. Also separated all user settable flags from MoreFlags into their own Flags variable. SVN r964 (trunk)
