    Various little fixes here and there:
    	- Basic support for dragging the selection is in (still does
    	  not do anything, will do the action binding later).
    	- Fixes to the cell-selection-code-when-you-type-a-formula code
    	- ExprTrees are now properly refcounted (instead of only
    	  refcounting the root node).  This is required for the
    	  Paste special/with-arithmetic operation feature.
    	- Expression decoding (for pasting a formula with relative
    	  references) now takes into account operator precedence to
    	  avoid cluttering the pasted expression with extra paretheses.
    	Other smallish fixes which I forget now.
