Merge pull request #167 from dshoreman/databases

Add basic database listing

Adds a basic (but filterable) table with a list of databases so the Databases item in the main sidebar menu finally has a purpose.

To get the list we add a new Database class that wraps Doctrine's DBAL which can eventually also be used to list tables etc.

This also sets up the ground work for #146.
