specifying {inherit: true} when generating href

Hey, the breadcrumb plugin works fine with ui-router 0.2.10. I'm trying to use the latest version because of some other fixes but it doesn't work anymore, and I suspect it will break with next release due to some changes in $state.href method. Anyways, my change does not break the current version and is working with the latest, so I think it doesn't hurt. Let me know if you think this makes sense or not.
