* Changes to make all tests pass again.
 * Bug fix in generator code

patched in Jonathan's test and case refactoring.  Renamed getmodelrate() to get_model_rate_dcuid() Created some tests for get_model_rate_dcuid().  Fixed Bug where slower models always had multiplier set to one.  awgtpman now sets multiplier based on 2kHz if model is slow. Improved includes a bit.

awgtpman calls getmodelrate(), which has been changed to fix two issues: the previous implementation could change the case of environment variables and crashed if either the IFO or SITE environment variables were undefined.

refactored getmodulerate() into /util/modelrate.c.  Affects local_dc, mx_stream, pub_sub_stream.  I was unable to build mx_stream due to missing openmx.  local_dc builds but is not tested.  pub_sub_stream builds and pasts ctest, but it also passed when getmodelrate() was an empty function.
