[OpenLayers-Dev] suggested patch to OpenLayers.Layer.ArcGIS93Rest

[G. Allegri]

I've noticed that the getUrl method in ArcGIS93Rest sets the thw
params BBOXSR and IMAGESR based on the map projection.
This is generally ok, but doesn't work if we want to use the "google
projection" (EPSG:900913). In such case we need to submit a specific
CSR to ArcGIS service: 102113
For my needs I've modified the method with the attached patch to check
if BBOXSR and IMAGESR params have been set as layer options.
