- [x] Provide data model and configuration toggle
- [x] Allow to delete individual test orders
- [x] Add tests
- [x] Add a prominent warning message to the backend if test mode orders exist (even though test mode is off), as this leads to wrong statistics
- [x] Decide if and how to generate invoices for test orders as invoice numbers cannot be repeated or should not have gaps.
- [x] Decide if and how we expose test orders through the API, since our difference pull mechanism relies on the fact that orders cannot be deleted.
- [x] Decide if and how we want to couple test modes of payment providers?
- [ ] pretix.eu: Ignore test orders for billing
- [ ] Adjust payment providers: Mollie, bitpay, cash, fakepayment, sepadebit

Placeholders in subject were not being replaced because there was
no `.format()` called on the subject.
This commit creates a context dict that is used for both the body
and the subject. It is then replaced using `.format_map()`
Fixes https://github.com/pretix/pretix/issues/531
* added signature field -- no function yet
* added mail signature feature
* fixed style issue
* fixed problem with signature default
* added unit test for mail signatures
* added unit test for mail signatures
`"-- "` on a single line as a signature-delimiter is noticed by a lot of mail programs out there as an actual signature separator and the text below may be marked that way, e.g. is greyed out a little in Mozilla Thunderbird.
This change should leverage that behavior for e-mails sent by pretix.
If the provided mail address has not ordered anything, there will still
be a mail generated and sent to an invalid mail address, to avoid
obvious timing attacks to determine active users.
