This commit is from the controller input PR #8807 from @garbear and changes the implementation of
CGUIWindowAddonBrowser::SelectAddonID()
to return-1
instead of0
if the select dialog hasn't been shown because there are no matching addons. Right now there's no way to distinguish between that case and the case where the user simply didn't select any addon and closed the dialog again.
