Notification RepoSpec is an `issues.RepoSpec` github.com/shurcooL/notificationsapp#5

Weird to have a dep on the issues app in this app. Was this just for convenience. Also sourcegraph.RepoSpec seems like the more generic struct to use.

Same reason as described in https://src.sourcegraph.com/apps/tracker/.tracker/30.

I think I had a TODO about "finding the best place to define RepoSpec". Yeah, it's here.

I saw platform apps as an opportunity to be more independent and take the chance to improve on various aspects; that includes not pulling in so many unneeded dependencies for basic struct definitions.

A short term solution I can think of is a go-sourcegraph-like package but for sourcegraph platform apps, so both tracker and notifications can use it. A more long term solution might be factoring out type definitions into a smaller package out of go-sourcegraph, and having everyone import that.

I'm okay with just leaving it as a TODO for the time being.

Cool :)

I very much like the idea of go-sourcegraph being less monolithic so pulling it in makes sense.
