The MakeThornList script written by Ian Kelley in 2002 can produce a minimal thornlist required to run a parameter file given that parameter file and a master thornlist. Unfortunately it does not handle the auto-activated REQUIRE thorns.

This pull request:

updates it to use Piraha to parse parameter file and configuration.ccl files to find the correct auto-activated thorns.
