Proxies are not supported on all browsers

[coffee-cup]

Proxies are only supported by 91% of browsers (#132 (comment)) https://caniuse.com/#search=Proxy. We try and polyfill Proxies so Prodo so Prodo will work on more browsers. There is a polyfill created by Google, but it does not have support for all traps.

Marking this as bug as not supporting 9% of browsers in a web framework is a real issue.
