Support Non-Email Usernames in Login Prompt

[JoelProminic]

While testing Super.Human.Portal on a customer server yesterday, Doug pointed out that we could login to names.nsf using the user name (like "Demo Admin"), but the Super.Human.Portal login prompt required that the username was an email address. This has been problem for the Super.Human.Installer instances as well, so I'd like to remove this restriction. I think the email address check is a carry-over from MyAccount.

This is not a priority, so i don't want to hold up the Moonshine.dev update (#62). I assigned this to the v1.2 milestone.

@JoelProminic I have pushed changes for this one.

This is currently a blocker for pushing out Super.Human.Portal and nomadhelper, so I need to keep this moving.
