Integrated a few external musrfit plug-ins into the standard build process.

In order to enable building of the additional libraries supply the following options to the configure script:

--enable-BMWlibs (for libTFitPofB libLFRelaxation libGapIntegrals libCalcMeanFieldsLEM)
--enable-ASlibs (for libPNL_PippardFitter)

By default, both options are disabled.

At the moment I have tested it only in an SL5 32-bit environment.
Further tests are going to follow.

For a clean installation I suggest to remove any musrfit and plug-in installations before newly building musrfit.
