WingStyle::__construct() is now updated - supports multiple arguments now.

It now does:
- WS("html")
- WS("html", "body")
- WS(array("html", "body"))
and the list is just so unlimited long :)
There is a little idea I have…you probably will see a lot of constants
that represent the normal HTML tags. So you might can just call
WS(html) without quotes :)
