Streamline Files interfaces

Summary:
  - There's no way you can figure out the ID of a file right now. Expose that
more prominently.
  - Put the drag-and-drop uploader on the main page so you don't have to click
through.
  - Restore the basic uploader so IE users can theoretically use the suite I
guess? Added author info to basic uploader.
  - Show author information in the table.
  - Show date information in the table.
  - Link file names.
  - Rename table for filter views.
  - When you upload one file, just jump to it. When you upload multiple files,
jump to your uploads and highlight them.
  - Add an "arc download" hint.

Test Plan: Uploaded single files, groups of files, and files via simple
uploader.
