Changes to support client-side image pre-caching in the region. This commit adds an additional calling sequence to the DynamicTexture data and URL calls. The new interface allows a dynamic image to be loaded into a specific object face (rather than the mandatory ALL_SIDES supported today. This is in part fulfilment of ticket #458.
