DBus signature for gtk objects

[Henrique Ser]

Hey,

Both slider-puzzle and jigsaw-puzzle do this when sharing a puzzle (or 
when using the Journal storage). It wasn't straightforward iirc, but 
feel free to dig in the code and ask if there is something cryptic there.

And it is slow, so be prepared...
