[sugar] [RELEASE] [MaMaMedia] Poll Builder, Slider Puzzle, Jigsaw Puzzle

[Morgan Collett]

I've released

http://dev.laptop.org/~morgan/bundles/Poll-18.xo
http://dev.laptop.org/~morgan/bundles/other/JigsawPuzzle-4.xo
http://dev.laptop.org/~morgan/bundles/other/SliderPuzzle-6.xo

with the license field added to activity.info, as per #8411, so that
these can possibly be included in the library (#8029).

Slider Puzzle gained a lot of translations since the last release.

Regards
Morgan
