fixed faceculling order on geometry for lines and caps, both even and odd segments. Added timed delete per line. Fixed networking bug where line data could be sent before remote clients were fully initialized. Adding drawing manager that prevents multiple pens from drawing on the same drawing at the same time.

correctly

Added activatable component, which allows a button to cause secondary activations to occur while an object is grabbed. Also made the pen "sticky" so it stays attached to your hand when you grab it. It can then only be dropped by using the "primary" grab button (e.g. grip buttons). The triggers now are "secondary_action" buttons, which work like normal except in the case that you are holding a sticky object, in which case they will not cause the object to be dropped.

needs lots of cleanup
