* Cuff enhancements

* Cuffs now have an OnClick for the alert to remove them
* nullables
* Use default interaction range so highlights are accurate
* Cuffing fails more gracely
* Make shared abstract and add component references to client / server
* Don't cache AudioSystem and HandsComponent given cuffs are rarely used

* Fix test
