PHP5-aware(ish) class member & multi-line parameter folding

[jesstelford]

Will now correctly recognise functions written like:
function foo (
$bar,
$baz,
$boo
) {
With up to 9 parameters.

And class variables like so;
class Foo {
/**
* @var String
*/
private $bar = "Something";

    /**
     * @var Int
     */
    public $baz = 10;

    /**
     * @var Float
     */
    protected $boo = 0.123;

This fix is great! It have been bothering me for a while.

I have zero control over vim-scripts/phpfolding.vim, it's just an autogenerated fake repository generated from vim.org. It seems I merged this manually at some point to 1.8. So consider this PR "MERGED" :)
