Title: Reduce ActiveModel version requirements

This commit gives possibility to use active_attr with rails 3.0.7 and higher (I wanted to use rails 3.0, but it has some serious difficulties with as_json method). There is no roles support for mass assignment, because active model 3.0 does not provide it.
