All output from stand-alone KPP is through log

There's a lot of clean-up to do, especially because I made some private
routines in the cvmix_kpp_drv module to help format some of the error logs.
There are two cool things about this setup, though:

1) Setting Verbosity='Warning' will remove all output
2) Setting Verbosity='EchoNamelist' will should the parameters used in each
   experiment.

Following on (2) above - I think I want to change the EchoNamelist status code
to EchoParameters.
