…her details are below. Also cleaned up composer.json so we don't import the entirety of ReactPHP, but rather only the parts we actually need.
The following changes were made to PHPCraft due to API changes and/or deprecations in ReactPHP:
・MultiplayerServer: [API breaking change as of 0.5.0] ReactPHP Socket listen() has been removed, with its functionality moved to the Server constructor. As such, the Server constructor format also changed, and its call location had to be moved in PHPCraft's code. — see https://github.com/reactphp/socket/releases/tag/v0.5.0
・MultiplayerServer, EntityManager: [API breaking change as of 0.5.0] ReactPHP EventLoop's nextTick() has been removed and replaced by futureTick() — see https://github.com/reactphp/event-loop/releases/tag/v0.5.0 and reactphp/event-loop#30
・MultiplayerServer: [API deprecation as of 1.2.0] ReactPHP EventLoop's Factory::create() has been deprecated and replaced by Loop::get() — see https://github.com/reactphp/event-loop/releases/tag/v1.2.0
