[haXe] Bug: Additional Args in some flash9 functions misssing

Added.

The haxe/std/flash9/*.hx API files have been automatically generated.
You can actually generate HX headers from any Flash9 SWF by running the
following command :

haxe --gen-hx-classes myas3.swf

You need to create a directory "tmp" first (since I forgot to remove it
before making the release ).

If some people are interested in reviewing the Flash9 API, there might
be some Dynamic that can be removed based on official documentation, in
particular all the content of Array's is right now Dynamic.
