Possibility to change sort order

[arvanus]

I really liked this sort order, and would like to add a option into bagmon to use this, without the need to change the code every time :) any idea?
Thanks

Sort.Proprieties = {
  'quality',
  'set',
  'level', 'name', 'id',
  'icon',
  'class', 'subclass', 'equip',
  'count'
}
