Merge pull request #829 from RosettaCommons/vmullig/clang_fix_master
Fix library levels and Mac clang builds
@davidekim: Please use the test server next time. Your merge messed up the library dependencies.
Restoring by moving cyclize_peptide() and fixH() functions from protocols/forge/methods/util.cc to protocols/relax/util.cc. In the process, I'm rewriting fixH() to use the proper functions in core for rebuilding polymer bond-dependent atoms (rather than manually placing the atom named "H" at a hardcoded position).
