Favicon Support

It's not a big deal since current browsers can use the shortcut link in the index.html head, but some people will be looking to have the favicon build directly into the root, rather than be in the images folder. Also, I have no idea how .ico would be handled currently, but again who cares really, browsers handle .png icons just fine.

Here is a possible solution that takes a source .png and creates the rest for us, however an even better solution would be one that takes a .svg as the source. https://github.com/haydenbleasel/favicons
