Beginnetje gemaakt met loop om events van devices te ontvangen en hun action door te sturen naar de huidige applicatie. Onderscheid gemaakt tussen events voor applicaties (start, pauze, enz) en events voor de main (exit, volgend device, enz). Misschien van event een betere uitgebreidere nuttigere wrapper maken voor een action.
