Added handling for space travel/stragglers.
Now new empty space levels are created if needed.
Added config option to use overmap system, ticked files in.

Conflicts:
	code/setup.dm
Added caching of zlevels.
Currently only condition to cache them is lack of client mobs there.
Updated templates for nanoUI changes.
Beepsky and ED209 are now closer friends than ever, now actually sharing code instead of each having gone and bought their own.

There is potential for breaking out all the special stuff for laser code but for now I'm happy to simply have a shared codebase.
I imagine pathfinding/patrolling may be sharable with bots in general as well.
Showers now cause wet floors. Mops can now be used to clean shuttles (non-simulated floor).
NewPipe
-Supply and scrubber pipes can be run in parallel without connecting to each other
-Supply pipes will only connect to supply pipes, vents and Universal Pipe Adapters(UPAs)
-Scrubber pipes will only connect to scrubber pipes, scrubbers and UPAs
-Supply and scrubber pipes are offset along the x and y axes to prevent sprite overlap
-UPAs will connect to regular, scrubber and supply pipes, as well as anything else that connects to a regular pipe. UPAs will be used to interface between the supply/scrubber loops and atmos
