Renamed block 1973:1 to Ancient Fabric. Renamed block 220 to Eternal
Fabric. I assigned new names so that we didn't need to use the long ones
we had before (e.g. "Fabric of Reality Permanent/Pushable"). Also
removed unused imports from various classes along the way.
Made some minor changes such as removing unused imports and fixing up
code to remove warnings. Stop calling static methods as if they were
instance methods!!! @_@
