## groupy branch migration
1. create a group -> group_id
2. delete new group's forum and assign old main forum to new group:

Forum.find_by_group_id(group_id).delete
g = Group.find(group_id)
f = Forum.first(:conditions => ['group_id IS ?',nil])
f.group = g
f.save

3. change all members' default accounts to belong to the new group:

    @e.amount = 1.0
    @e.customer = @p2

    @membership.roles = ['individual']
    @membership.save

    account = @p2.account(@g)
    account.balance = 0.0
    account.credit_limit = 0.5
    account.save!

      unless exchange.group
        # the presence of group is validated when creating an exchange
        # group will be nil for the new method, so allow it
        true
      else
