comment: Make comment directives no longer use the internal "_comment" form, and document the comment directive syntax.

Rationalle: Comments need to be user-editable so that they can be posted
via git commit etc.

The _comment directive is still supported, for back-compat.

+The `comment` directive is supplied by the
+[[!iki plugins/comment desc=comment]] plugin, and is used to add a comment
+to a page. Typically, the directive is the only thing on a comment page,
+and is filled out by the comment plugin when a user posts a comment.
+
+Example:
+
+	\[[!comment format=mdwn
+	username="foo"
+	subject="Bar"
+	date="2009-06-02T19:05:01Z"
+	content="""
+	Blah blah.
+	"""
+	]]
+
+## usage
+
+The only required parameter is `content`, the others just add or override
+metadata of the comment.
+
+* `content` - Text to display for the comment.
+  Note that [[directives|ikiwiki/directive]]
+  may not be allowed, depending on the configuration
+  of the comment plugin.
+* `format` - Specifies the markup used for the content.
+* `subject` - Subject for the comment.
+* `date` - Date the comment was posted. Can be entered in
+  nearly any format, since it's parsed by [[!cpan TimeDate]]
+* `username` - Used to record the username (or OpenID)
+  of a logged in commenter.
+* `ip` - Can be used to record the IP address of a commenter,
+  if they posted anonymously.
+* `claimedauthor` - Records the name that the user entered,
+  if anonmous commenters are allowed to enter their (unverified)
+  name.
