USC-gtk3 doesn't allow for tabbing between the stars in the rating window

hi mpt. did some work on this (see linked branch). the keynav interactions will need some testing. i know the star visually is prob not quite what you are after but i think it will do for now.

Matthew, that's a big improvement, and probably landable by itself. Thank you.

The next step would be a focus ring around the whole stars widget, so you can tell that it's focused even before any stars are filled.

In <https://wiki.ubuntu.com/SoftwareCenter/RatingsAndReviews#reviews-reviewing> I also suggested hooking up the 1, 2, 3, 4, and 5 keys.

1,2,3,4,5 keys are now hooked up. as for focus i have made the stars border go orange when focus. or would you still prefer a focus ring around the whole idget.

Good work on the number keys. As for the arrow keys, I think it makes more sense for the star widget to behave like a slider than a menu. So rather than the stars being items that you highlight and then activate with Space/Enter, they should be values that you change immediately with Left and Right. Does that seem reasonable?

If so, effectively it is the whole widget being focused, not individual stars, so the focus ring should be around the whole set of stars, like it is around a GTK slider.

That version is no more maintained
