Backbone Model/Collection change events should pass along remote:true from the Hoodie store event

[espy]

Listening to hoodie.store.on directly, you get an options object with remote: true in it if the change came from, well, remote. This is super valuable because it lets you know whether you've got to re-render the current view or not (if the change came from the current client, you really don't want to).

However, when using Backbone's internal model/collection change events, you can no longer distinguish between remote and local changes, which makes things a bit complicated.
