Title: Allowed a tab-title to be watched

Not sure if there is a better way (tried using observes and watches and I can't get it to work), but we have a requirement to allow the title of a tab to change - internal language service - and the current ion-tab-nav doesn't do this.

I've changed the binding to two-way and it works...
