Plasma Events

[Davnik]

We want to express just how common plasma is in the HGAZ, by perhaps adding random events which spawn plasma crystals (and drifting plasmodic entities?) to make spacewalking a pain and perhaps flood some rooms with plasma (so players are more hardened to the usual plasma griffening), as well as perhaps some plasma-based antagonists. Big projects, longterm for sure, and we'll need to discuss (or make sub-projects) to provide all the details and meat of these systems.
