fix notifications in a background tab (#402)
Part of the way to improving #390.

Before this fix, if you recieved a notification while Pinafore was in a background tab, nothing would happen, because most browsers (Edge, Firefox, Chrome) don't run rAF in background tabs. Furthermore, Chrome doesn't run rIC. In this PR we detect if we're in a background tab and then avoid rAF/rIC in that case.
