correct some spelling errors in material.config
adopted marc2008 interface routine
removed sequential interface routines as they are not needed any more
I restructured the subroutine in view of non local constitutive models.
ATTENTION OpenMP parallelization does not work with this version, needs some more work.
ATTENTION CPFEM_GIA8.f90 is not addopted to the new scheme and will NOT work, should actually be renamed CPFEM_RGC.f90 ;-)
I removed crystallite.f90, the routines are now in CPFEM_*.f90.
I removed the marc2005 interface routine since it is outdated.
