Move Storage docs from wiki to main docs

[Elrond]

We decided to move documentation, that is finished and more technical into the main docs.

So, move ​http://wiki.mediagoblin.org/Storage into docs/source/devel/storage.
The workbench is there for starters.

I'd like to take this on!

I've started learning a bit about Sphinx and .rst format and I'd love to learn more about making pretty docs :

Well here's the solution that I've come up w/ so far, let me know if it works!

Heya,

Good job on this! I just merged it.

One comment: in general, it's best to try to keep your line-length short on commit messages... generally try to wrap them at column 80, that makes them easy to read when using tools like tig, magit, other git log tools :)

Good work, and thanks again!

[Christopher Allan Webber]

Also, I see on other commits you wrapped at column 80, so nm, I guess this was URL related! :)

Ah thanks, yeah I pushed both this and #601 at the same time before I knew about that practice for commit messages and I got told about it on #601, so I didn't change this message, but now I know to that for the future, thanks for checking this out :)
