Message:

Instead of duplicating code we now enable OpenLayers.js to be used in both the Single File Library build and the dynamic load version. A SFL build is now indicated by way of the existence of a _OPENLAYERS_SFL_ flag. Instead of using a try/catch block to avoid polluting the global namespace the dynamic load code now uses an anonymous function. The dynamic loading code also no longer checks for the existence of OpenLayers.Map, it will now always run when it is not in a SFL build.
