Fix #1487 and only add the delete cursor if the block is not deletabl… (#1491)

Browse Source 
* Fix #1487 and only add the delete cursor if the block is not deletable. Also add a grab cursor when it is not deletable so the cursor keeps the grab hand when over the toolbox.  This changes the toolbox api slightly, but the methods it touches are @package so it should be okay.
