Too many warning dialogs reading trajectory of PDB files

[Tom Goddard]

I tried reading 230 PDB files (part of a trajectory) using the File / Open dialog. Each one has some invalid REMARK records and each one generates a separate warning dialog -- 230 warning dialogs I have to click Ok on.

Chimera 1 does not have this problem because the warnings go to the Reply Log instead of showing a warning dialog. Maybe ChimeraX should use that method. If a dialog is deemed desirable then the warnings for the multiple models should be coalesced.

After getting into this state quitting the program (right click icon / Quit) just gets rid of one warning dialog on Mac -- so it is necessary to Force Quit to recover.

Using command

log warningDialog false

before opening the offending PDB models avoids the problem.

Moved collation up to a higher level (models.open), so all these warnings are now coalesced into a single dialog.
