[svn r121] Finished ModuleInfo implementation. Static ctors/dtors now work according to spec. Changed class vtable types slightly in some cases. Overridden functions now always take the the type of the first class declaring the method as this parameter. This helps when using headers (w. implementation somewhere else)

module classes10;

class C
{
    int i;
    override char[] toString()
    {
        return "foobar";
    }
}

void main()
{
    Object o = new C;
    char[] s = o.toString();
    assert(s == "foobar");
}
