#110 Use label element in comment submission form

[dolphinling]

Use the label element in edit_comment;comments;default
on "No Karma Bonus", "Post Anonomously", and "No
Subscriber Bonus".

This increases the target area, making them easier to hit.

I'm a complete newb to slashcode, perl, cvs, diff, etc,
etc, etc, so check all 1476 bytes of it extra
carefully. ;-)
