[gimp/wip/animation: 325/373] plug-ins: single-click on track title selects all, and double-click...



commit 9a89a8e63806d1bed9f21c66be3c2c4525ef05ee

    plug-ins: single-click on track title selects all, and double-click...
    
    ... to edit the title.
    In order to not trigger a select-all action on double click as well, I
    delay it though I'm really not sure it's a good experience to do so.
    Maybe I will review this later.
