Added new field for css classes & redirect as resp

[JurajKavka]

• After successfull processing the form, plugin responses with redirect instead of standard response. This approach prevents form resubmission with page reload.

This one is exactly what I was looking for! How can I use this without waiting for merge?

Hi,

you can use my fork of this repository here but i don't maintain it. You can clone it and use python setup.py install to install it into your virtual enviroment...

It's old commit I hope it will work with your version of cms :D

Good luck!
