Bug#828158: caja: backgrounds and emblems dialog does not work

[Vlad Orlov]

This had been partially fixed upstream. While the backgrounds & emblems dialog still
needs resizing to make the contents appear, the actual applying of colors, backgrounds
and emblems to folders now works as before. You can drag-n-drop a color or a background
pattern from the dialog to the icon view, and the directory background will be changed.
Drag-n-dropping of emblems to files and folders works as well.

Same as with #856027, the following packages are needed:

mate-desktop 1.16.2
mate-settings-daemon 1.16.2
caja 1.16.3


Since Caja 1.16.3 requires build and runtime deps on mate-desktop 1.16.2,
the following change to debian/control is suggested:
