integrates class level definition of cms_attributes

From now on cms attributes are not defined in Ruby mixins anymore, but directly in the model file using "cms_attribute" class method. Pass in the name of the attribute and a params hash to define the type, values, max_size and min_size.

+ fixes specs
+ adds changelog
+ removes outdated attribute and attribute api generator
+ removes some german translation files that don't need to be supported, they add complexity, which should be handled by the implementing project team
