Account for preprocessor directives
doxygen is currently unaware of preprocessor defines in Fortran code. configure should substitute this in the doxygen configuration file.

doxygen will not run its built-in preprocessor on the Fortran code because it will only do so on Fortran files with upper-case extensions (i.e.
*.F90). To work around this, I came up with a method which runs the actual compiler preprocessor with relevant preprocessor macro definitions passed on the command line for each Fortran
*.f90 file, using the
FILTER_PATTERNS tag. See the attached patch. Note that some of the macro definitions are related to the patch in #347, but it should not cause problems having additional definitions passed on the command line which are not used.
