Show full image node detail buttons in the sidebar. The image nodes in compositor, cycles and texture nodes were showing a very reduced version of the image data block UI, based on the idea of fitting it
into the confined space of a node. However, in the side bar panel there is no reason to limit the buttons. In fact it is very helpful to have this UI available, otherwise users have to have an image
editor or (BI) texture buttons window next to the node editor to access these image details.
