For example, if you search filter some images out then the selection manager will only display the visible count and deleting/removing in a batch will only operate on the visible and selected items.
-Moved batch deletion behaviour - it is now a responsibility of the current context to implement
-Updated feed deletion behaviour - in the Feed context only now the image is not deleted from disk but instead simly removed from the frontend and backend image lists. the image can still be retrieved from Temp/History, but deleting it from that context will remove it from disk.
-Added blank implementations for Model contexts - will implement properly later.
-Separated out the act of deleting an image from disk and removing it from the image list as individual functions
-Add Remove From List as a flyout or batch command. Doesn't delete, just takes it out of the current list.
-imageElement.deleteItem now returns a booolean describing the function's success
