Cannot preview Follow up Comments

yup, i can reproduce on a test site. that's good. ;) without having looked closely at the code, this should be relatively easy to fix. i'll try to roll a patch in the near future, unless someone else beats me to it.

can someone else please review/test this?

1. makes project_comment_validate() just use a reference, to be a little more simple
2. converts $edit from an array to an object in the case of project_comment_form_add_preview(), so we can always use it as an object
3. a few minor variables renamed

seems to solve the problem on my php5 test site, and still works on my php4 site. but, it's after 2am here, so i'd like independent verification before i commit it. ;)

thanks,
