started replacing ember-easy-form-extensions by ember-form-master-2000
and ember-validations by ember-cp-validations
using ember-form-master-2000 in old 0.2 release cause newer releases does not work with ember 0.12
should move to ember 2.x as soon as possible
therefore ember-easy-form-extensions has to be dropped and ember-i18n been updated
part of #76
ember-i18n pluralization seems to add another key to languages object (without pluralization)
not sure why this modified languages object is retrieved by test
810aa7f04b (pluralization)
before it was done as computed properties of model
accessing encryption key in serializer is done via global application var.
this should be removed in long-term
