Bryan's first rune.  Elevator that ferries player up and down based on
open spaces.  Doesn't consume energy.  Very complex 3D template.
Renamed KEY to FUEL because it has nothing to do with keys.
Very important fix for Key-- now FuelBlock recognition on all runes.
Builder Rune working much better now.  NESW facing detection implemented
by changing checkRunePattern signature.  Possible regressions:
aetherSay.  Runecraft not rotating facing.
minor spelling
