Set up text clipping for very long locations

[evanblack]

Set up some text clipping for when locations in the header of the weather view are super long.

Tested with some longer city/town locations (Kleinfeltersville, PA and Fredericksburg, VA), which still fit, so I think this is fairly low priority.

Need to add a right padding to the header element to account for the timestamp. Add these CSS properties:
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;

Also may need to absolutely postion the timestamp as opposed to float.
