Add web fullscreen support (#1142)

Browse source 
Adds fullscreen using native web APIs to the stdweb and web-sys backends.

Due to limitations of browser APIs, requests for fullscreen can only be fulfilled during a short-lived user-triggered event. This commit does automatically handle that under the hood, but it does introduce unavoidable latency in full-screening the canvas.
