Title: Ember.SortableMixin: Add support of custom sortFunction

The default sorting algorithm used in the Routable mixin (based on Ember.compare) was not satisfying in our case.
For example we want 'a' to appear before 'B' (in ascending order)

I think this PR is not complete as we have to handle each type of sortProperties.
