Merge pull request #4602 from RosettaCommons/jadolfbr/sugar_bb_defaults
Change sugar_bb default and add intra_rep term if not present
- Change sugar_bb weights to .5, as this is ideal for both ref_2015 and beta. Turn on `fa_intra_rep_xover4` at 0.55 if not present when using `-include_sugars`.
- Generally recommend the beta/Rosetta-ICO ScoreFunction if intra_rep is off.
All three of these (sugar_bb .5, intra_rep, and generally -beta) improve decoy discrimination significantly when de-novo modeling sugars, or building sugars into density.
