Motivation: I often find myself annoyed by `delete-selection-mode' when
using the keyboard since the region in Emacs does not translate to text
selections in other applications.  On the contrary, I find myself
wanting the behaviour of `delete-selection-mode' for regions set using
the mouse.  Attached patch adds an user option to do that.
