This adds support for https://github.com/bcardarella/client_side_validations you showed in one of your screencasts. It also adds support for using the assets pipeline. I probably removed all backwards compatibility so you'll probably want to use parts of these changes.
Almost forgot, I also changed where the new fields are added. Instead of just adding before the link I prefer to add the fields to a container with id xxx-fields.
Add support for client_side_validations and use assets pipeline.
Add engine to serve assets.
Please implement this asap :-)
For a lighter-weight approach to client_side_validations support, see #211 and https://github.com/ryanb/nested_form/wiki/Integrating-with-client_side_validations.
Thanks to @taavo nested_form and client_side_validations are able to work together now.
