Facilitate user defined type factories

[Helveg]

Add patch.monkey entry point because

A) It's a pun I can't resist
B) The p property can then be monkey patched before it is imported by scripts.

The advertised objects should be factories for callables that take the PythonHocInterpreter as argument. The factories themselves are passed the entire PythonHocModule because they can't import patch (circular import as this entry point is called during import of the patch module).

Patch should also get a submodule monkey with in it a method patch because what's better than a pun? A double pun! And with patch.monkey.patch you should be able to watertightly patch some stuff like all the functions that can start a simulation

Monkey patching might have adverse effects when patch is used in multiple projects and generally has adverse side effects. Great pun, bad idea.

Instead inheritance to create your own patch.interpreter.PythonHocInterpreter could be used, a type map could be added and all patched wrappers could check if they need to return patch.objects.* or a user defined type instead.
