[00871][R#181] Perfromance issues (especially creeper caves)

[eNTi]

my gfx hard and cpu are getting mad in creeper caves sometimes. the fans are blowing like mad, textures are flickering, are replaced by nothing but white or extra large icons. i think the main reason is decals and to some extend other effects. this is especially apparent if you are hitting huge numbers of mobs with rk drones. those leave black decals from the impact and blood decals from the creepers which overlap so often, that they bring my gt470 and my i5 2.4ghz core to its knees. there's to easy solutions in two steps:

1. remove the decals from the game entirely until you can implement:
2. a decal count for a zone that has either a performance related limit, a hard coded (low) limit or a player set limit (neocron.ini)
