Minor Improvement Patch

Server
- Optimized creature update loop in preparation for upcoming changes to creature AI.

Architecture
- Placement refresh function optimized to reduce delays when placing and moving building parts.
- Inconsistencies with building movement corrected. Occasional situation where a part turns invalid (red) during the final build (and must be moved back and forth) corrected.
- Zone boundary issues corrected. Projects spanning zone boundaries should no longer become invalid (red) if properly supported.
- Issue causing players teleporting to infirmaries build above platforms falling through the platforms fixed.
