Integrate Regrid to store and stream big files

[janek26]

Or another filesystem for RethinkDB.

Advances to buffer -> You can stream data o or from the database

ReGrid -> https://github.com/internalfx/regrid

That's not really in the scope of thinky.

There are many blob stores to choose from. I wrote my own, scalable-blob-store, not to mention Amazon or Azure.

If someone would like to use regrid they can simply add the module.

Like @grantcarthew, there's no reason to merge these two modules together. If someone needs both, they should just import both.
