v3.1.0 RELEASE

[jonahseguin]

Notable changes:

• Improved handshake system
• Removed object handshake system
• Converted to Lettuce.io for Redis from Jedis, allows for improved performance
• Debug now cache-specific, enabling debug in the config will enable debug globally
• New 'updater' system for pushing an object across servers on a network manually
• Remove sync system in favour of manual updater system
• Profiles/Objects aren't stored in Redis anymore, only MongoDB. Redis is now used to keep track of the state of objects/players. (i.e online state, last seen server, etc.)
• Updated Morphia
• Make use of Google Guice + dependency injection throughout most of the project. Not necessary for use when using Payload, but recommended.
