Add sorting of doc_methods on a repo by documentation status

[thenickcox]

This commit adds sorting on a repo between documented and undocumented methods, via a simple UI.

Closes #21.

The build failed, but I stashed my changes, and it still failed, so I don't believe the failure is related to my commit.

While I'm waiting, I'll see if I can determine the cause of the failing test. Should be able to look into this in the next day or two.

@thenickcox Looks like the test was failing all the time. d34c68a3 is the commit that added this test.

@prathamesh-sonpatki Fixed it. It was an issue with the way I wrote the fixture data. Looks like it's good to merge, should you so desire.

[prathamesh-sonpatki]

Interesting, what was the difference in fixtures?

[thenickcox]

@prathamesh-sonpatki I get different output on that commit:

So I don't actually get a difference in the fixtures.

My first commit made the test fail because the doc_methods fixtures belonged to a repo that the user was already subscribed to. Thus, calling User.queue.subscribe_docs(user.id) didn't change the user's doc_assignments. It was 2, and it remained 2 after calling that method. My most recent change (to fix this test) was assigning them to a repo the user wasn't already subscribed to, so that calling User.queue.subscribe_docs(user.id) had the intended effect of changing the user's doc_assignments by 1, from 0 to 1.
