treat all DBs as time varying. There is a new check box in
the GUI's preferences window and a new CLI method,
SetTreatAllDBsAsTimeVarying(), plus a test of this feature
was added to tests/databases/wave_tv.py

Some changes were also made to add regular expression parsing
of cycle numbers from filenames and a new CL arg, '-cycleregex'
was added too control this from the CL.

An unused data file in FLASH.tar.bz2 was removed also.
