[security-dev] SHA salted passwords

That shouldn't be too hard, we just need to amend the 
PasswordCredentialHandler by adding String to the list of supported 
credential types, i.e:

@SupportsCredentials({ UsernamePasswordCredentials.class, 
Password.class, String.class })

Then we need to add support for String credentials to the update() method.

I think it might actually be a good idea to remove hashed passwords as an option and instead offer things more secure such as bcrypt or scrypt. One of those at least, imo, should be default. Hashed passwords, even with a salt are really not that secure and I'm not talking about rainbow table attacks, just plain brute force attacks with small box lots of GPU power and some coda code are quickly become the norm for brute forcing passwords.

The code you pointed out is already doing that:https://github.com/picketlink/TODO/blob/master/server/src/main/java/org/aerogear/todo/server/security/register/RegistrationEndpoint.java#L85  Behind the scenes it is using SHA-512 and a SecureRandom-1024 salt. Unfortunately, you can not change such configuration for now. Regards.

So, the PlainTextPassword can be used to store encoded password which algorithm will be used behind!
