4.1.0: Socket connections

• Added support for xp-forge/uri version 3.0+ - @thekid
• Heads up: Deprecated passing origin to WebSocket constructor. It
  should be passed inside the headers when calling connect().
  (@thekid)
• Merged PR #7: Added ability to pass path and query string to WebSocket
  constructor
  (@thekid)
• Fixed "Call to a member function message() on null" errors when using
  an already connected socket in the WebSocket constructor.
