Make includes free to the user (application support component)

Summary:
We spend a significant amount of time running includes, even with APC. However, we have rigidly structured includes and can safely run them all in workers before requests occur.

Right now, requests go like this:

  - Apache spawns a worker.
  - Client sends an HTTP request.
  - Apache interprets it.
  - Apache sees it's ".php", so it hands it off to the PHP SAPI.
  - The PHP SAPI starts the PHP interpreter in the worker.
  - The request is handled, etc.

Instead, we want to do this:

  - Worker spawns and loads the world.
  - Client sends an HTTP request.
  - Webeserver interprets it.
  - Sees it's a ".php", hands it off to the SAPI.
  - SAPI executes it on a loaded world.

No SAPIs I know of support this, but I added support to PHP-FPM fairly easily (in the sense that it took me 6 hours and I have a hacky, barely-working mess). Over HTTP (vs HTTPS) the performance improvement is pretty dramatic.

HPHP doesn't significantly defray this cost so we're probably quite a bit faster (to the user) under nginx+PHP-FPM than HPHP after this works for real.

I have the php-fpm half of this patch in a messy state, I'm going to try to port it to be vs php 5.4.

Test Plan: Ran a patched php-fpm, browsed around, site works, appears dramatically faster.

Add "Flags" to allow users to collect the things they love

Summary:
Flags are a personal collection of things you want to take a look at later. You can use several different colors and add notes.

Not really sure if this is actually a good idea or not but it was easy to build.

Planned features:

  - Allow Herald rules to add flags.
  - In the "edit flag" dialog, have a "[x] Subscribe Me" checkbox that CCs you.
  - Support Diffusion.
  - Support Phriction.
  - Always show flags on an object if you have them (in every view)?
  - Edit dialog feels a little heavy?
  - More filtering in /flag/ tool.
  - Add a top-level links somewhere?

Test Plan: Added, edited and removed flags from things. Viewed flags in flag view.

Improve inline comment previews

Summary:
  - When an inline comment preview corresponds to an inline comment on the page, link to it. Just punt in the tough case where the inline is on some other page.
  - In "haunted" mode, "z" now toggles through three modes: normal, comment area only, and comment + previews.

Test Plan:
  - Viewed visible and not-visible inline comment previews, clicked "View" links.
  - Tapped "z" a bunch to toggle haunt modes.

Don't trim indentation in `arc amend`

Show other open revisions affecting the same files in Differential

Summary:
I think this feature is probably good, but Differential is also really starting to get a lot of stuff which is not the diff in it. Not sure how best to deal with that.

The mixed table styles are also pretty ugly.

So I guess this is more feedback / proof-of-concept, I think I want to try to improve it somehow before I land it.

Test Plan: Looked at some diffs, some had an awkward, ugly list of diffs affecting the same files.

Don't add author and reviewers to CCs in Herald

Summary:
Herald rules are adding CC also for Author and Reviewer.
See also D1397.
I was considering also just don't displaying the extra CC but this is probably better.

There are still cases where there could be reviewer in CC (e.g. by making reviewer from CC or by direct edit) but I think it's not a big problem.

Beeing both Reviewer and CC can be actually useful (e.g. if you resign than you still are in CC) but it's not that useful to justify this:

  Author: vrana
  Reviewers: epriestley
  CCs: vrana, epriestley

General Herald refactoring pass

Summary:
**Who can delete global rules?**: I discussed this with @jungejason. The current behavior is that the rule author or any administrator can delete a global rule, but this
isn't consistent with who can edit a rule (anyone) and doesn't really make much sense (it's an artifact of the global/personal split). I proposed that anyone can delete a
rule but we don't actually delete them, and log the deletion. However, when it came time to actually write the code for this I backed off a bit and continued actually
deleting the rules -- I think this does a reasonable job of balancing accountability with complexity. So the new impelmentation is:

  - Personal rules can be deleted only by their owners.
  - Global rules can be deleted by any user.
  - All deletes are logged.
  - Logs are more detailed.
  - All logged actions can be viewed in aggregate.

**Minor Cleanup**

  - Merged `HomeController` and `AllController`.
  - Moved most queries to Query classes.
  - Use AphrontFormSelectControl::renderSelectTag() where appropriate (this is a fairly recent addition).
  - Use an AphrontErrorView to render the dry run notice (this didn't exist when I ported).
  - Reenable some transaction code (this works again now).
  - Removed the ability for admins to change rule authors (this was a little buggy, messy, and doesn't make tons of sense after the personal/global rule split).
  - Rules which depend on other rules now display the right options (all global rules, all your personal rules for personal rules).
  - Fix a bug in AphrontTableView where the "no data" cell would be rendered too wide if some columns are not visible.
  - Allow selectFilter() in AphrontNavFilterView to be called without a 'default' argument.

Test Plan:
  - Browsed, created, edited, deleted personal and gules.
  - Verified generated logs.
  - Did some dry runs.
  - Verified transcript list and transcript details.
  - Created/edited all/any rules; created/edited once/every time rules.
  - Filtered admin views by users.
