--User changes

-Draw selection circles around all selected xforms plus the current one.

--Bug fixes
 -Add control key as a modifier to increase the amount a spinbox is changed when using right mouse drag to edit. Previously only observed shift key to decrease the value.
 -Change the copy/paste selected xforms shortcuts to be Ctrl+X+C and Ctrl+X+V.

--Code changes
 -Add function Fractorium::IsXformSelected() to determine if an xform has been selected with the checkboxes.
