Cleaning up the contents of test.
including "CheckEither", written against scalacheck 1.2 in the year 471
AD. Removed all the duplicates I could find, mostly between pending
and files. Renamed a bunch of tests so they wouldn't look like likely
duplicates next time around. Nominated somebody else to do this once in
a while.
No review.
