Default styling for <q> is removed

[acdha]

Currently generated quotes are reset for both <blockquote> and <q>:

bootstrap/less/type.less

Lines 257 to 263 in 88854a8

	// Quotes
	q:before,
	q:after,
	blockquote:before,
	blockquote:after {
	content: "";
	}

// Quotes
q:before,
q:after,
blockquote:before,
blockquote:after {
  content: "";
}

Unfortunately no styling is set for <q>, making the tag effectively invisible. Since the browser default :before { content: open-quote; } :after { content: close-quote; } is adequate, the fix should be as simple as removing the q: selectors.
