Title: Implemented the attributes attribute for a 2 ways binding, fixes #8. 

Implemented the attributes attribute for a 2 ways binding, fixes #8.
Didn't implemented the published option as I think it will only be a duplication of attribute (in fact polymer docs suggests to use attributes instead).

As a bonus I've implemented the on{attributeName}Changed callback as Polymer.
