Merge pull request #3844 from RosettaCommons/JWLabonte/PDB_IO
PDB IO: Smarter Title Section generation
This merge will deal with two requests that I have received following PR #2468.
- An option, `-write_pdb_title_section_records`, is provided, which may be set to false by those who wish to skip any title section at all in their `.pdb` files.
- A framework is set up to have Rosetta write `REMARK 3` records instead of `REMARK 220` records, if the `Pose` contains crystal density. (This will not work fully until PR #3627 is merged.)
It also corrects the output of parametric data, forcing it to use `REMARK 250` records for output.
All integration test changes involve the change in Crick parameter output, as expected. All other tests pass that weren't already seriously broken. (Someone(s), please fix!)
