Location for Things

I have just created a new stable ESH build, which is part of the openHAB Distro since build #386.

Main functional change is the introduction of a new field on Things for their physical location.

This is (for now) only a text field where you can put in any string. The main feature for which this is used now is that you will find your things grouped by their location on the Control part of the Paper UI - so this let’s you structure your view there and not all Things are on the same page anymore.
Note that the idea is that it is representing the physical location, while the items (with their group items for rooms) are the functional view - so both are a different information (think of your actuator (physical) in the cellar that switches the light (functional) in the living room).
