Module reload should reload module source.py too.

When you do a change in python code of a module, upgrading the module don't change the code in memory. You need to restart Open Object server. That's not great when you are doing some updates. Every user must be disconnected.

A solution could be to watch which python module are loaded when loading a Open Object module. Then reload those module.

Here is a subject about such problem:
