Víðir Valberg Guðmundsson b2fa1dc92c WIP Reimbursement feature (#278)
* Almost done, need the send to economic part.

* Add a way to approve/reject an reimbursement and send mails accordingly.

* finish work on custom invoice address

* add textfield notes to Order for internal orga notes about the order

* Almost done, need the send to economic part.

* Add a way to approve/reject an reimbursement and send mails accordingly.

* economy commit of doom.. replace reimbursement app with an economy app, add Expense and Reimbursement models, add management of expenses and reimbursements to backoffice. Rework and cleanup permissions stuff, add Camp.Permissions pseudo model to hold all our non-model permissions. still experimental, expect rough edges, but basic functionality should work.
