Building should negate all spawn functions.

[Darena]

When a building part is placed inside of, or close on top of, the ground surface, all respawns in that area should be shut down. This should include plants, resource points like Acorns, insect or animal spawn points such as for Larvae... everything. The points are *not* removed, and if the building part is moved, the respawn timers will be reset, allowing things to grow and spawn there again normally.

ALL building parts should be included in this, but especially foundations, scaffolding, and floors should have this effect, along with any other 'base level' building blocks that a player might use as a foundation for the rest of the base to be constructed on.
