Line-ending issues for resaved PDB files

[jonathan@…]

The following bug report has been submitted:
Platform:        Windows-10-10.0.18362
ChimeraX Version: 1.0rc202005190628 (2020-05-19 06:28:14 UTC)
Description
PDB export end of line delimiters are inconsistent.

I opened a trivial PDB with "\n" (not "\n\r") end of line delimiters.  I ran "addh" at the command prompt then saved the PDB with a different name.

The "ATOM" and "TERM" and "END" lines in the exported PDB had "\n" only.
The "HEADER", "TITLE" and "COMPND" lines had "\n\r".

For another file that also had "CONECT" lines, the exported version had "\n" only for the "CONECT" lines.

The endings are now uniformly just newline. Fix available in next daily build and release candidate.
