* reran the simple form initializer.
* wrapped submit buttons are now broken and need a fix.
* disabled confirmation validation in client side validations as the
  error message always is attached to the wrong field.

fixes #16

This used to trigger a 500.

Fixes #8395

We saw errors from duplicate loading of LocalEmail and
LoginFormatValidation. The latter resulted in a crash.

In an attempt to ensure all subclasses of Couchrest::Model::Base are
loaded Couchrest::Model::Utils::Migrate requires all files in app/models.
We have an extension that does the same for the engines.

During this process LoginFormatValidation and LocalEmail were autoloaded
when 'identity' was required. Afterwards they were required again.
It looks like rails' autoload mechanism does not play nicely with require.

So to make sure they are not autoloaded first move the concerns and
helper classes into the lib directory and require them explicitly.

MX validations relied on network connection. Only using them
in production environment now. I want to be able to develop and
test when disconnected.

We still have strange urls requested like
 /pt/users/AnonymousUser.../tickets/new

Not sure where they are coming from - but this should make sure we
respond with sth. meaningful instead of erroring out.

CouchRest > 1.2 does not use RestClient anymore. So we should not try to
catch its errors.
