Changes

Well, this will probably anger the Grim Reaper, but I have finally
removed the SICL from CLUBB (as discussed a number of months ago).

That term is now expunged from the entirety of CLUBB, including all
source code, stats files, and postprocessing files.

This change is technically BIT_CHANGING because two stats variables,
wprtp_sicl and wpthlp_sicl, have been removed from stats output files.

However, all results remain exactly the same.
