Remove loading of bangers font by default in main boot class.

[JakeLaCombe]

I was looking through the code of the Boot state, and saw that it was trying to load the bangers font family. (https://github.com/lean/phaser-es6-webpack/blob/master/src/states/Boot.js#L14). Lately, the font has been taking a while to download, causing this game to to freeze on the loading fonts page.

Since this is the starting template for a game to build using webpack and phaser, perhaps it could be ideal if we remove the default behavior of loading a font library?
