Merge remote-tracking branch 'origin/feature/8763_Refl_gui_Many_minor_improvments'
refs #8763. Two code-behind changes.

Im really breaking the rules doing this directly on master. I shouldnt be making this change on master, but we badly need them tonight for user testing tomorrow. This is BAD practice, but I dont have much choice.
refs #8780. Add ability to coadd via commas and colons
Merge branch 'feature/8780_coadd_in_quick' into develop
