Subject: Fixed PR #273. Moved the graphic drivers into hardware since they are
 hardware specific, in the long run maybe we move them into 'drivers' or
 something. And moved the user interaction from gfx_drivers into
 user_interactions. And removed the import from installer.py to __init__.py
 since we don't want to import 'global functions' in extension imports.
