[krita/krita/3.2] plugins/dockers/imagedocker: FEATURE: save lastly visited directory in the Reference Images docker

[Dmitry Kazakov]

Git commit 3b6d3646bc54d46616c145b9d75b2491fef5476e by Dmitry Kazakov.
Committed on 03/08/2017 at 17:04.
Pushed by dkazakov into branch 'krita/3.2'.

FEATURE: save lastly visited directory in the Reference Images docker

Now the docker saves/restores the lastly visited reference folder
over Krita restart.

** A question to painters **

Do you also need to restore the open reference images?

Please take into account that at the moment the list of reference
images is not per-painting, it is global, that is shared between all
open images in Krita.
