Improve rmv_vers function

The rmv_vers function could use some improvement…

Old Code:

function rmv_vers( $src ){
		$parts = explode( '?', $src );
		return $parts[0];
	}

Suggested update:

function rmv_vers( $src ){
		if ( strpos( $src, '?ver=' ) ) {
			$src = esc_url( remove_query_arg( 'ver', $src ) );
		}
		return $src;
	}

Not only is it a bit better, but also there is a bug in WordPress where when loading a Google font its adding “&ver=4.2.1” instead of “?ver=4.2.1” at the end of the string. The current code will break the script completely, but the updated version won’t break things because it’s targeting the specific query argument.

Thanks!!
