James D. Callahan III:
	- Stop making throwaway sort functions every time Archy:UpdateSiteDistances() is called - now there's zero garbage-generation when moving around.
	- Check if in an instance to terminate from UpdateDistanceIndicator() BEFORE computing distances with Astrolabe.
	- Moved the contents of SetDistanceIndicatorText() inline to its only calling position and removed the function.
	- Minor code-formatting changes, logic cleanups, and better variable names.
	- Removed duplicate updating of the site frame's distance value.
	- Kill a bunch of string garbage-generation by using :SetFormattedText() where applicable (when updating site distances, reduced from 1.4k/sec to 0.3k/sec).
