eeschema: Set modifying transparency on edits

Browse Source 
While modifying elements in eeschema/libedit, they are overdrawn on the
rest of the schematic.  This prevents alignment with existing elements
as the underlying elements are not visible.  We set a slight
transparency on elements while being modified to allow the user to view
existing elements at the same time.
