Allows userdefined classes

With this commit the user can add his own classes by:
- adding the class in the user_classes.conf file
- dealing with a numbered script in usercustomization/class/ folder (for example usercustomization/class/99-custom, chmod 755) to use the class
- adding all the files related to the classes in the usercustomization hierarchy
