User:TomTheHand/Unit tests for AWB regexes/Geographical coordinates

This section contains regular expressions for converting plain-text geographical coordinates to coord.

I had originally hoped to be able to combine all of this functionality into one gigantic, extremely awesome expression. I'm not sure if it's possible, but I've definitely given up. These do make sure that you enter valid coordinates, which I'm pleased with.

I originally just had them require the correct number of digits (up to two for latitude and up to three for longitude), but then you could still input something like 91° N, 181° W. Fixing that problem made me feel sufficiently spiffy that I could give up on my gigantic regex dream without much guilt.
