user modules.
* Don't delete vars when we delete a module. This makes
reinstalling a module a lot easier.
* Add user::lookup() as the preferred way to load a user, so that
other modules don't delve into the user module (that'd be a
problem when we swap out user modules)
* Notify site admins if Akismet is not fully configured
* Bundle all server variables into the comment so that if/when we
re-check the comment, we are not using the server info from the
site admin's request.
* Update Akismet to grab request context data from the comment
* Pre-seed comment fields if we have a logged in user. Update
comment::create() API to clarify it for this.
* Delete comment::update(), that's a controller function.
* Add url to User_Model
* Add author_name() author_email() and author_url() to
Comment_Model. It'll return the appropriate values depending
on whether the comment was left by a logged in user or a guest.
* Use resetForm() instead of clearForm() when we reload the
comment form after ajax submit, this way we preserve the
pre-seeded values.
* In the user profile page, ignore blank passwords.
The comment block has changed to only display comments that are visible.

associates them with the form. This replaces the various _add_validation_rules()
functions in the user and comment modules.
Move user edit form into user helper for consistency with the comment module.
Implement missing _form method in the user controller.
