Mongoid Paranoia Sync

I'm adding some aliases to scopes so that the methods sync with Mongoid Paranoia methods. We're using polygot databases and I think it's nicer to have consistent methods across components tasked with doing the same thing.

Maybe one day I'll combine the two gems to work with ActiveRecord & Mongoid.

Also contains formatting changes.  If you use different formatting settings with your IDE I can adjust.
