Quick fixes for Map Helper:
- Fixed PostCleanupMap that being executed outside from defined gamemodes.
- Fixed for PropHunters that Secret Door can be unlocked on Spawn. This wasn't intended for PropHunt gamemode anyways.
- Added Gamemode Name verification checks for proper checking.

Quick some fixes for the following:
- Adjusted areaportal_window's start & end fade distance by +100 units
- Fixed 1 Spawn point for Murder gamemode that can cause player to get stuck
- Fixed (and moved) few Spawn points for TTT gamemode that can cause player to get stuck in the wall/floor

I also forgot to mention that the map is currently on beta stage, this was a quick fix from the LUA and Entity Edit so it's kinda impossible to compile at this moment.
