LibWeb: Support :active pseudo-class for hyperlinks, :focus possibly

Browse source 
Adds support for the :active pseudo-class for hyperlinks (<a> tags
only).

Also, since it was very similar to :focus and an element having a
focused state was already implemented, I went ahead and implemented
that pseudo-class too, although I cannot come up with a working
example to validate it.
