Title: Attribdict improvements

Following http://stackoverflow.com/questions/7148419/subclass-dict-userdict-dict-or-abc, I started refactoring the current AttribDict implementation to a class inheriting from http://docs.python.org/2/library/collections.html#collections.MutableMapping.

The resulting class seems to me much more readable and maintainable and runs a bit faster - tests are running for me.
