add %c handling to console, add color support for proxy console

[Prozi]

I've added support for:

console.log('%cthis is colored text', 'color: red; background: pink;')

since I work with pixi.js (pixi-shim) and they have a pretty colored hello message that was looking plain ugly

to see the message in action

1. add library pixi-shim

import {Application} from 'pixi-shim'
new Application

3. see console tab

fixed console.log('%c') corner case

added %s string replace
