Files - kill tabs

Summary:
kill tabs for Files application.  Technique is the "filter list" on the left
hand side, with separation for "Files" versus "Image Macros".   UI quirks
include:

- the page title does not change for the 3 files filters while it does change
for each of the two image macro filters.
- standalone "file" pages do not have the filter view
- you can visit /file/upload/ standalone and it doesn't have the pretty filter
list on it

Please do give direction on these quirks if you like.  :)

This change also neuters the ?author= functionality for files.  The code is
written such that it can easily be brought back.

Test Plan: clicked around on the filters, liked what I saw.  uploaded files
fancy-like and basic-like and it worked!  made image macros and it worked!
