Input events still firing when sim.active=false

[samreid]

I put sim.active=false and that prevents the clock from running, but scenery is still processing input events (I can click on things and they respond).

It looks like Input.js is still processing events directly when triggerImmediate is true.

@jonathanolson recommended using a semitransparent overlay div that will intercept input events.

Scenery side should be accomplished with display.interactive.

I'm using display.interactive above and it is working nicely, thanks @jonathanolson! Closing.
