* Turned on the MapImageModule as opposed to the code in Scene for generating the map image. Copied the code in Scene into the MapImageModule, made a few tweaks to get it to work with the module's interface. 

* Refactored a few things in Scene to make maptile saving easier to understand.
* Added comments to describe the 'clever code' assetcache update without the gridasset being updated so as to lessen possible confusion in patches in the future.
* If the MapImageModule isn't loaded, default to the code in Scene still.
