Select all available bodies when rendering a feed story

Summary:
Fixes T4060. The logic here is:

  - When you take several actions at once, we show a single feed story for all of them.
  - We choose the "most interesting" title for the feed story. For example, "close task" is more interesting than "add CC".

Currently, the issue with this is:

  - "Add comment" is the //least interesting// title. I think this is correct: all other actions are more interesting than the fact that you added a comment.
  - We try to conserve the number of objects we need to load by rendering only the most interesting transaction.

To fix this:

  - Stop being so conservative; load all of the transactions and all of their PHIDs.
  - Add bodies from any transactions which render bodies. In all cases (I think?) this is a maximum of one comment adding a body.

The end result is a story like this:

Implement basic Harbormaster daemon and start builds.

Summary: This implements a basic Harbormaster daemon that takes pending builds and builds them (currently just sleeps 15 seconds before moving to passed state).  It also implements an interface to apply a build plan to a buildable, so that users can kick off builds for a buildable.

Test Plan: Ran `bin/phd debug PhabricatorHarbormasterBuildDaemon` and used the interface to start some builds by applying a build plan.  Observed them move from 'pending' to 'building' to 'passed'.

Land Revision button for hosted git repos

Summary:
ref T182.

Simple approach of clone, patch, push. While waiting for drydock, implement a hackish mutex
setup for the workspace, which should work ok as long as there's only one committer who is
carefull about theses things.

Less obvious note: This is taking the both author and commiter's 'primary email' for the commit -
which might rub some people wrong.

Test Plan:
With a hosted repo, created some diffs and landed them.
Also clicked button for some error cases, got the right error message.

Add build step implementation infrastructure and sleep build step.

Summary:
Depends on D7498.

This implements support for a "build step implementation".  Build steps have an associated class name (which makes the class in PHP) and a details field, which is serialized JSON (same as PhabricatorRepository).

This also implements a SleepBuildStepImplementation which just pauses the build for a specified period of seconds.

Test Plan:
Inserted a build step with `insert into harbormaster_buildstep (phid, buildPlanPHID, className, details, dateCreated, dateModified) values ('', 'PHID-HMCP-zkh5w6czfbfpk2gxwdeo', 'SleepBuildStepImplementation', '{"seconds":5}', NOW(), NOW());` (adjusting the build plan PHID as appropriate).

Started the daemon and applied the build plan to a buildable, and saw the daemon take a 5 second delay after creating `SleepBuildStepImplementation`.

Summary: Ref T4064. The response code here isn't normally relevant, but we can hit these via `git clone http://../`, etc., and it's clearly more correct to use HTTP 500.

Test Plan: Added a fake `throw new Exception()` and verified I got an HTTP 500 response.
