Send emails when commits are ingested

[philc]

When pulling in new commits, we should send emails when a commit is ingested. Matching these commits to saved searches will be expensive, and so should be a separate background job, not part of the commit importer.

I'll be working on some substantial changes to how email jobs are queued this weekend, which would affect the design of this process. Consult with me before beginning on this.

[philc]

I'll take this.

I'm going to port our jobs to Redis. At that point I'll add in support for emails upon commit ingestion.

Did you mean "resque"? I guess that runs on Redis.

[philc]

Yep, meant Resque.

This is complete as of d5da83a.

This doesn't seem to work, maybe because the "email me on new commits" box isn't visible anywhere?

[cespare]

This is not deployed yet (it's going out tonight).
