Title: Implemented server-side timestampting

Added `Mongoid::Timestapms::Serverside` with spec for it.

To use you should include 1Mongoid::Timestapms::Serverside` before any field definitions.

This concern add field `ts` with type `Moped::BSON::Timestamp` which is updated on each save operation.
