Support for mongoid_5.0.0

[andreale]

Hi folks. This is an updated version of mongoid-autoinc that supports mongoid_5.0.0 (currently still in beta)

The underlying driver has changed from Moped to the official MongoDB Ruby driver. http://docs.mongodb.org/ecosystem/tutorial/ruby-mongoid-tutorial/#upgrading-to-5-0-0
