Description:
------------
You can call non static classes like
System.Collections.Stack
or
System.Text.StringBuilder

But no static classes like System.Console.

Reproduce code:
---------------
<?php
  $console = new DOTNET("mscorlib", "System.Console");
  $console->WriteLine("Hello World!");
?>

Expected result:
----------------
Hello World!

Actual result:
--------------
Fatal error: Uncaught exception 'com_exception' with message 'Failed to instanti
ate .Net object [CreateInstance] [0x80131513] ' in C:\Users\Brutos\Desktop\test.php:2
Stack trace:
#0 C:\Users\Brutos\Desktop\test.php(2): dotnet->dotnet('mscorlib', 'System.Console')
#1 {main}
  thrown in C:\Users\Brutos\Desktop\test.php on line 2

It needs help of the wrapper class to be done.

Assigning to cmb for review as he's the new maintainer for COM.

Indeed, COM does not support static methods.  While there are
certainly ways to overcome this limitation, the details need to be
discussed on the internals@ mailing list[1].  Anybody is welcome
to start that discussion.  For the time being, I'm suspending this
ticket.
