Subject: Add "Enable notifications" checkbox in "Add Comment" form

Currently, it is a little to easy to forget to enable notifications
for a package after leaving a comment, thus never being notified of a
reply. Even though the "Enable notifications" link is on the same
page, it is not part of the flow for posting a new comment, and so,
easy to miss.

Most web forums and comment systems include a checkbox to enable
notifications when posting for the first time in a thread. This patch
implements this in aurweb, as well.
