Binding to List names

[neverfox]

Often times, the your intent is to leverage the name of an object in Firebase as an "id" property of the object. But List essentially shunts these off into a names array, so that you don't have coordinated access to them in an #each loop over the content. Does one essentially need to adopt a different approach with ember-firebase of always explicitly storing a value for an id alongside other properties, if that's what you need? Or is there something clever I'm not thinking of to get this kind of access?
