 It would be great to stop further filter-hooks/action-observer when we
 reached a state that should not continue.

 This helps especially for custom implementations:

 * Rejection actions that should not run.
 * Return filtered values without giving other plugins the chance to change
 them.

 All just for specific cases.

 Possible implementation:

 * Normal but impossible: Event-Class as wrapper reflecting whether to
 continue or stop.
 * Semi-normal-way: Throwing a exception like
 `\WP_Stop_Propagation_Exception` telling WP_Hook to stop.
 * Absolute absurd way: Setting a global variable like `$stop_propagation =
 true`

 ... and there may be more.
