* reran the simple form initializer.

enable testing error responses on the full rack stack.

If you inherit respond to and call it again in your controller
it will not overwrite the previous but add to it.

Since we always have some exceptions from the rules it's probably
easiest to be explicit in the controllers that require it themselves.

with_config is not mean to test the current config. It will
set the config. So instead we need to look into APP_CONFIG.

There was a lot of special case handling going on in the users_controller
for this. Lot simpler this way.

This way we do not need to specify it all the times.

In the functional tests defaults do not get added automatically.
Introduced api_{get,put,post,delete} to add format and version default.

One to two functional tests failing, everything else passes.

It somehow managed to fail for a certain test order. Seems rather
rare though - have not been able to reproduce it in 5 runs.

Failed with --seed 60219.

This way the changed flash hash still is recognized.

Also changed the generic 'no_such_thing' i18n key to more specific 'no_such_user'.
The former is very hard to translate as the gender of thing may affect the translation of the 'no such' part.
