Merge pull request #768 from RosettaCommons/possu@u.washington.edu/repeat_update
updates to remodel to include repeat protein building features
1) Remodel repeat features
2) improved symmetry handling in repeats
3) change default chain behavior to A
4) change CCDclosure mover output levels (it's otherwise hard to use the output)
integration test changes: almost all are cosmetic from changing the output levels of CCD closure mover. Remodel related test changes are expected.
