Log Message:
-----------
Fix "duplicate strip" always increase the user count for ipo.

As venomgfx point, the shift+d function never duplicate the ipo block
if we have enable the option in UserDef -> Edit Methods -> Ipo.

Now, if Ipo option is disable, we just increase the user count, otherwise
we duplicate the ipo.

Note: Alighorith, we need call ipo_idnew here ? (like single_ipo_users)
