Addons Framework

Add Object Utils

At the moment the add_utils.py in /addons/modules is more or less a direct copy of add_object_utils.py in /scripts/modules. I did this so i can edit it (don't have access to bf-blender svn).

The two main Objects are the AddObjectHelper class and the add_object_data function. The AddObjectHelper class adds mandatory location and rotation RNA properties to the oparator. add_object_data adds the Object into the scene according to user preferences. This function lets us remove lots of duplicated code in the various add_addons.
