replacement for my own autocomplete module by stani

Browse Source 
--- from his patch
All the functionality is in the console
folder:
- intellisense.py: the central module which loads others on demand
- complete_namespace: more or less a replacement for the old autocomplete.py
- complete_import: module completion (I find this very handy, not just luxury)

These complete_* modules work very simple and should also work outside blender. You give some  input and it returns a list with possible completions.

autocomplete.py is now deprecated.
