Build w/ gradle and Locale-independent toString

Build with gradle is self explanatory. I need it for my project since the artifact is not on maven central. You might want to consider putting it there, since it's a VERY useful library when developing Android apps using public API:s in Sweden.

The second part is to make the toString methods of WGS84 always return decimal number as 1.234 instead of sometimes "1.234", "1,234" or even "1·234". This lets all test cases work regardless of locale on build host.
