Forget about my old version.... I have read more articles, and I was doing it wrong. The salt should be random on every user, so no fixed salts !
	This new code uses SHA256 encryption and a 64 character salt... this is super safe.
	I have made the salting autoupdate... so no difficult migrations, if they login, the new, improved, password is generated.
	I also made the minimum password length to 6  (was 4).
	LINK to code: security 0623 v3
	Again, this is AS IS... And I donate it to the Cotonti community   (BEWARE THIS IS FOR GENOA: 0.6.23).
	Please test all stuff first... I might have made mistakes !  (logging in and logging out is tested)
	Run the SQL file to update the database first
	Let me know your test results !
	If all goes well this should really be in 0.6.24 !!!   only a md5 is just NOT safe anymore !
