Usability should be objects, not strings

This is almost ready - there should probably be a thing saying how "showable" should be interpreted if "single" is not specified for double-blind (like, maybe there's a "once" that can be used to state that you only need to enter one if "showable" is present).

Actually, "once" should be a thing regardless of showable status - you can either double-blind enter a password, or you can once-showable it, or you can enter it once blind and take your chances (the way "single" sites work).

"showable" without "once" or "single" is interpreted to mean something like guru.com: while you can show the password, you still have to enter it twice (and in Guru's stupid case, you have to do the second time blind).

Maybe "secondblind" should be a property that only Guru has (otherwise "showable" is understood to refer to both). Anyway, it can be added at a later point if it's still the case.

Also I'll note that I think I've seen blind email entry before (at a theme park?) - this might get spec'd later.
