Up to [LON-CAPA] / loncom / interface

- No breadcrumbs trail in modal pop-up when previewing aboutme, syllabus,
  roster, and pdf documents from links in Course Editor.
- Breadcrumbs trails for "Supplemental" and "Main" content more consistent:
  - No Main Menu link as first item if symb or folderpath available
  - No Return to Last location link/icon if symb or folderpath available
- Don't set supplementalflag to 1 for documents uploaded to Main Content
  area which require "showdoc", so breadcrumb trail is available to students.
