Title: Add ability to pass childOptions along to child collection

When creating new subcollection/subset, you may be using a subclass
of Backbone.Collection – and this might require options to be
specified.

If childOptions are specifed (and a child option is not), the
childOptions will be passed along to the child constructor.
