Style and power transforms

[WouterRademaker]

This will add arguments for "style" and "power transforms"

{{#fab:wikipedia-w|color:blue|grow-6}} will render as <i class="fab fa-wikipedia-w" style="color:blue" data-fa-transform="grow-6"></i> when using the javascript rendermode and as <i class="fab fa-wikipedia-w" style="color:blue"></i> when using the webfont rendermode.

Because the Chameleon skin still uses Font Awesome v5, some advanced effects such as stacking do not work as expected with the javascript render mode when using the Chameleon skin.

More or less solves "Colors and fontsíze #6"
