Change default comment form styling
Add ajax response to add comment action

Not needed, but useful for debugging
Remove debug logging code
Change js animations on first load

1. Hide the comment form on page load
2. Hide loading icon div on success
3. Fade In commnet form in success callback
Remove "on load" beforeSend callback

Seemed like a good idea at the time...
Cast "data" as local var
Add cach false parameter for ajax call
Add debug logging code

Temporary - to be removed at later date
