Merge pull request #255 from RosettaCommons/justinrporter/env_release
Merge miscellaneous bug fixing related to Environment, except a bug in FoldTree::insert_fold_tree_by_jump that creates an invalid fold tree when the inserted fold tree is a single, one-residue peptide edge. This is fixed by commit 90120df.
Integration test failures are expected from antibody_graft and inverse_rotamer_remodel for unrelated reasons, as well as "core_scoring_Score_10000x_fa_cust_pair_dist," which seems to be failing these days.
