Render avatar, profile and self in format json

[echox]

Fix for Issue #164 (added self and avatar to json)

[mvitz]

Thanks for your contribution.

1. I think the self link should point to the 'status' and not to the 'author'!
2. I personally favour that each commit is buildable. Maybe you could squash the first two and the last two together?
3. Maybe you could add some tests for the JSON rendering.

I'm going to merge this PR once at least 1. is fixed.

[echox]

Ok:

1. You are correct, I still keep the profile link as an addition :-)
2. done.
3. done, a test for routes.clj should be also added at some point.

FWIW, I think it's more important for commits to be atomic. However, it's nice if the set of commits being pushed (hopefully still reasonably small) is CI compliant.

[mvitz]

I agree. But for me atomic includes that the code works...

I never would commit a call to a new function first and the function itself in a separate commit afterwards.

@echox is this PR complete or is there anything missing?

[echox]

should be complete :-)

Thanks, I will have a look at it at the weekend.
