- disabled Heretic's 'joke' cheats and Chex's 'idmus' in 'allcheats' mode because their multiple occurence interfered with how the cheat parser works.
- merge cheat fix from maint.
- fixed: Application of inflictor's death damage type was done too late and missed a few spots where it needed.
- fixed: DamageTypeReceived was not serialized.
- fixed: The check for unhandled damage type was rendered ineffective by the old code handling the DeathType.
- added new MAPINFO/gameinfo keys for adding entries to some string arrays, most notably the player classes and the F1 info pages.
- fixed: Draining health from a victim must check for damage reduction before awarding the health to the player. This affected Heretic's gauntlets, A_Saw and A_CustomPunch.
- added a DONTDRAIN flag that prevents the above attacks from draining any health at all.
