Projects: Filter out archived projects from all project view

Summary: Adds an "allactive" filter in addition to the all projects filter.

Test Plan:
visit All Active view (/project/filter/allactive/) and
 see that it lists all projects except those which have been archived.
 Visit other filter views to be sure nothing else got broken.

Project symbol import from 'ctags'

Summary:
I noticed that documentation said it is possible to have 'ctags' symbol import, so I hacked a quick version. I tested it on Python based project and successfuly imported symbols.

It is limited to classes right now, as the importer script complained about not-unique method names (there are a lot of 'get' & 'post' methods accross classes in my project).

If you would have any feedback about this, I would definetly try to wrap it up for possibly merging into main repository.

Test Plan:
Required 'ctags' tool (ctags.sourceforge.net/) Tested to work with version 5.8+ and didn't work with 3.x.

1. `find . -type f '*.py' | ./generate_ctags_symbols.php > /tmp/symbols`
2. `./import_project_symbols.php` < /tmp/symbols

Add "Resign from Audit" and "Close Audit" actions to Diffusion

Summary:
See some discussion in D2002. Add two new actions:

  - Resign: (auditor only) closes your open request (user request ONLY) by putting it in a "resigned" state.
  - Close: (author only) closes all open requests by putting them in a "closed" state.

@davidreuss, this is probably conflict-city with D2002 -- I'll wait for you to land first and then handle the merge on my end.

Test Plan: Resigned from and closed audits.

Add an "Explicit-CCs" header to Differential

Summary: This header allows recipients to distinguish between CCs generated by Herald and CCs generated by humans.

Test Plan: Created a Herald rule to add a bunch of CC's to every revision. Created a revision. Added some CCs manually. Verified that only manual CCs appeared in the "Explicit" header.
