Removed event enumeration and getEventType() method.
Routines::getEventType() method and event enumerations were used within Thaed::startGameLoop()'s calculation phase, which was replaced by Routine::isReadyToUpdate(). Because they were replaced, they are no longer needed, and were removed as a result.
Removed Routines::getEventType().
Thanks to Routines::isReadyToUpdate(), there is no longer a need for a public proxy for al_event.type. As such, Routines::getEventType() was effectively removed.
