Merge lp:~chrisccoulson/libdbusmenu/ffox-fixes into lp:libdbusmenu/0.5

[David Barth]

See the change description in Chris's bug report at https://bugs.launchpad.net/ubuntu/+source/libdbusmenu/+bug/690447

[Karl Lattimer (karl-qdh)]

I have one question about this patch, in line 38 you remove the ITEM_ACTIVATED signal. Does anything in existence utilise this signal and would need to be changed to use ABOUT_TO_SHOW instead?

review: Needs Information

[Ted Gould (ted)]

Karl, you're right in that things will need to change. Mostly what needs to change is appmenu-gtk and libappindicator as they don't connect to the about-to-show signal (yet) and thus only pass that to applications with the activate signal. But, this patch should still go in as we need the feature elsewhere.

Also, I'm not going to merge the "ABI saving" feature of replacing the reserved as the current trunk already breaks the ABI :)
