Add geo-location-javascript project

Source is extracted from the download zip file but is identical to the current versions in the repo, apart from some svn updated variables:

* zip file: http://code.google.com/p/geo-location-javascript/downloads/detail?name=geo-location-javascript_0_4_08.zip&can=2&q=
* dev: http://geo-location-javascript.googlecode.com/svn/trunk/js/geo.js (svn variables filled in)
* minified: http://geo-location-javascript.googlecode.com/svn/trunk/js/geo-min.js (identical)

Not that downloaded (~3k for current version) but starred by 390 people. We still use it :)
