Integrate Typeplate for base typographic styles

I added typeplate to the scss chain, had to change some rules in _typeplate.scss for sass to render style.css:

&:before {
		content: '&#x93;';
		top:  0;
		left: 0;
	}
	&:after {
		content: '&#x94;';
		bottom: 0;
		right: 0;
	}

Original was:
&:before {
		content: '“';
		top:  0;
		left: 0;
	}
	&:after {
		content: '”';
		bottom: 0;
		right: 0;
	}

Threw an UTF-8 encoding error while rendering style.css
