PARMG cleanup, write out deformationfunction to a file, Continue the trustregionsolver with a smaller trustregion radius in case of an exception

• Clean up PARMG compiler-flags
• Write out the deformation to a file; this can then be read by dune-gfe
• Continue the trustregionsolver with a smaller trustregion radius in case of an exception @oliver.sander_at_tu-dresden.de: Can you have a look?
