ember-paper constants service may collides with existing service

I'm adding ember-paper to an existing ember app where a constant service is already existing.

It's overriding the one from ember-paper which force me to update my own service and modify a bunch of calls.

I already encountered this issue a while ago and it was said (if I recall correctly) that this service was supposed to be replaced by something else.

Anyway since it still there I create this issue as a reminder.
