Summary : Add-on Prefs

[neomonkeus]

Blender 2.67 introduced add-on preferences which allow saving values specific to the add-on.
API for Addon-Preferences
http://www.blender.org/documentation/blender_python_api_2_71_release/bpy.types.AddonPreferences.html

This should allow:

• Save any values altered by the user.
• Defining/Loading of presets
• Loading default values

We can discuss her what sort of prefences we would like to see.
