Title: It would be nice to use abstract states in ui-sref in some cases

Live example in my project

States are:
profile - abstract
profile.index
profile.more

With this change I can easily show menu item as selected for all profile substates.
profile

And setup default child in configuration.

.state('profile', {
url : "/profile",
abstract:true,
templateUrl : '/app/profile.html',
defaultChild : 'index',
}).
