Backup and restore icons positions and settings

Suggestions:
  1. Backup settings you made (see Nova Settings -> Backup & import settings) , it also backups all icons positions you arrange.
    When you Restore Nova launcher with tools like Titanium backup you will be missing icons of not yet installed applications, but when you restore settings natively missing apps icons will be in it's places (slightly greyed out).
