Subject: Big set of changes to comments, with related changes to akismet and
 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.
