#3483: Integration with javascript module loaders (AMD)

 _getScriptLocation works only if !OpenLayers is defined in a <script> tag,
 making the library incompatible with AMD's require(). In a practical case:
 we use Dojo 1.7 and have to load maps on demand.

 Tweaking _getScriptLocation is easy and everything works fine (hard code
 as quick and dirty workaround).
 It could be resolved elegantly by using an optional predefined
 configuration variable (olConfig, like Dojo's djConfig).

 Another related point, specific to Dojo: we had to register !OpenLayers
 explicitly in the global scope because of a security feature (with this
 solution: add "window.!OpenLayers=!OpenLayers" at the end of the main

 Finally, i feel that a library like !OpenLayers would greatly benefit from
 using extensively AMD specs: automatically loading required modules only,
 thus reducing the network load and improving the speed, permitting the use
 of flexible build systems, improving the integration with javascript
 frameworks and adding server side capabilities, among probably other
