HTML-Parser-3.02

[Gisle Aas]

HTML-Parser-3.02 is now on CPAN.  Fix HTML-Tree compatibility.

    Hide ~-magic IV-pointer to 'struct p_state' behind a reference.
    This allow copying of the internal _hparser_xs_state element, and
    will make HTML-Tree-0.61 to work again.

    Introduced $p->init() which might be useful for subclasses that
    only want the initialization part of the constructor.

    Filled out DIAGNOSTICS section of the HTML::Parser POD.
