Wrap entire location display in a div

As a themer, it's maddening to find a display of related content not wrapped in a div which can easily be themed. In the case of the locations.tpl.php, there is no wrapping div surrounding both the <h3> title and the location display itself. It results in something pretty themer-unfriendly (for example, imagine wanting to place the location display somewhere, such as in a visual box or float the whole thing....)

The attached patch adds a wrapper div to bring both title and display together so it's easier to theme.
