Removal of all the old threading code!!!

This will all eventually be replaced by Gary Thompson's multi_processor code, once it is ported to
the new relax design. This threading code was broken, buggy, and not fault tolerant anyway.

Renamed 'print_flag' to 'verbosity' in the calc(), grid_search(), and minimise() user functions.

This arg is not really a flag, and it is the verbosity level, so this makes more sense.
