qmail-hashdir: Stuff still to be done,

 - Documentation:
	Not happy with this at present, esp. mention of the alias user
	and the hash user - since these may be the same user.  I should
	be able to clarify this somehow...
 - Installation procedure:
	I'd like to have DJB-style conf- files. If I get plenty of free
	time, this could be an option. Don't hold your breath though.
 - Dash:
	I want to spend some time getting the dash character logic
	straightened out. Soon, maybe...
 - Commands:
	I want to add more commands, and also to alter how they work:
	Each user will in future have a set of files relating to their
	settings, based on which a .qmail file can be constructed
	(thank you Shreos Roychowdhury for that breakthrough). This
	makes construction of a .qmail file atomic and therefore avoids
	possible locking issues if multiple admin machines update
	the same user's data.
