Upgrade to Mongoid 5.x

Mongoid 5 is a major upgrade to Mongoid for several reasons :

• Moped is not used anymore. The driver is the brand new official MongoDB ruby driver 2.0
• Mongoid is now officialy maintained by Mongodb

Here is a non comprehensive list of things to chexk or upgrade.

• Mongoid.yml. The driver changes, so the options you pass to mongoid.yml also do. You should generate a brand new one and find the equivalent options you were using. The sessions entry has been replaced by the clients entry.
• Aggregation. User.collection.aggregate now requires an array as argument, not a variable number of hashes
• Moped:: classes like Errors or BSON don't exist anymore.
