EndwormRE and Huskbrood emperor removal related changes. Replaced with more ice whales early on and Enforcer spawns later on, deal with it!

removed a number of old BTC monsters and gave spawns to other monsters being unused or underutilized.

Update didn't fire? more spinelings early game like in vanilla, some more mines in odd places. more prawn spawns and much more. I took inventory of what we had in BTC and tried to get a decent amount of new spawn types. Will be taking a much more indepth stock later and trying to improve the first three biomes so its less mine spawn on biome 2.

fixes for several abandoned station missions.
