docstring: Tries to login user using token.
  
  Token must be passed as a GET parameter named `token`, tokens looks as follow:
  
  // <md5-hash> (length = 32)

  Tokens are consumables, the same token cannot be used twice to log in.
  
  @param \Cake\Network\Request $request A request object
  @return bool True if user was logged in using token, false otherwise
