fomalhaut v4 changelog

v4
- Fixed the BFG secret door so you can no longer open it by pressing use (I changed this so there's a different secret switch you have to find to open it, but forgot to remove the action on the door).
- Changed up the Revs near the RS door at the exit to appear once you open the RS door.
- Made it so that you can not easily use the choke off point in the RK arena to fight the monsters.  You now need the RK to get into that area.
- Hopefully made the monsters that spawn in near the FIREBLUE spawner able to get out of the pit a bit easier with some additional stairs.
- Added some more Imps in the spawning cavern fights.
- Added just tiny bits more ammo around the map in key areas.
- Added just tiny bits more health around the map in key areas.
- Made various minor texture adjustments.
