Also handle the case where the regex does not match in OpenLayers.js::_getScriptLocation, and use a shorter variable name for the match. In addition to the reviewed patch, also added some comments about simplification in 3.0, and to make jorix happy. Finally, moved VERSION_NUMBER to the top to make it easy to see it in a minified build. r=elemoine (closes #2873)
