Support for version 0.15 of the server, and major rework! This version introduces a wide range of conditions and expressions that make it easier to handle messages and state changes.
(Due to breaking changes introduced on this version of the SDK, it has been renamed to "Colyseus_SDK". If you are migrating from version 0.14 to 0.15 of the SDK, it is best to have both "Colyseus" (0.14) and "Colyseus_SDK" (0.15) installed, and manually modify the references from the old plugin to the new one)
