Major Update to Chunks Input Type

All of these updates make this input work in PyroCMS 2.2.4. Everything should work here. I used some AJAX calls to append new chunks while editing a page. There is still a little styling to be added to the backend, but everything works. I also changed the module author name. You are welcome to change that back if you'd like. I had forgotten that this was a fork of your earlier work. :smile:
