Methods Added to Schema Should Return Promises

[killercup]

Almost all Mongoose methods return promises (using the mpromisemodule), but the methods added by this module don't.

E.g.: User.findOne({name: me}).exec() vs. User.findByUsername(name, callback)

It's not a big deal, just something I noticed. I guess this could be easily added without changing the callback arguments.

Sounds good, I'm taking a look how to implement that.

This would be nice as it would also allow the use of async/await
