SQL CHANGES: New table CommentNotify with fields:

	PkgID
	UserID
This implements emailing comment notifications, including a user option to
enable/disable it on the package page. It uses php's mail() function to do
it and sends to everyone on the notify list as BCC.

This needs some more testing before public consumption.
