Be polite to users with order dependent tests

`i_suck_and_my_tests_are_order_dependent` is still aliased and usable.

This is a sort-of followup to the immature issue #398.

In several projects I need my tests to run in a specific order (e.g. integration tests).

Yes, #398 was inappropriate, but I like the idea being less offensive and more polite to users.

Opinions?
