Better adapter for the Navigation Drawer. Updating titles according clicks.

I kind of struggle a lot here because there were lots of alternatives. The one I most like is using a custom adapter that encapsulates all the handling of ListViews. Because this is a Navigation Drawer with different Fragments I couldn't do my magic.

The most clean approach I found was using a Array adapter, keeping the elements as a ArrayList and referencing everything to their positions.

Besides adding functionality, I need to do lots of improvements by adapting the current code for avoiding not synchronized behavior of the view with the DB.
Small changes.
