Active conferences (#7684)

* Add active conferences with web sockets

* Buttons mostly working

* Convert all methods, function, variable, const to snake case instead of standards.

* Add default settings for customized control

* Add customizable settings

* More debugging default settings added

* Add better authentication handling for websocket connections
These methods were added:
- on_ws_authenticated can be overridden in the child class if there are tasks that need to be done after authentication.
- handle_ws_authenticated was added in the parent class

Handle methods are called by the this class and then their respective 'on_ws_' method is then called.

* Mute All now working

* Add PHPDoc block comments

* More PHPDoc to better describe class and variables

* Fix accidental removal of function during PHPDoc block edits

* Remove the variable type declaration for PHP 7.1 compatibility

* Update conferences with more websocket communication to replace AJAX calls.

* Ensure interface is loaded when no members

* Move color settings to theme category

* Update page view to default settings changes
