Description

Rename the DataAccess namespace to Gravity. Additionally this restructures the whole namespace into clearer sub-namespaces to not have everything in the same folder.
The new structure is like this:

Gravity
 |_Database
 | |_MySQL
 |_Filesystem

Eventually we could make sub-namespaces in Gravity\Filesystem as well, but IMHO it's still a bit early for that.

This depends on http://reviews.lunr.nl/r/67/ and http://reviews.lunr.nl/r/63/

Testing Done
