Title: Issue 2561 unique logins

Reopening unique logins pull:

Adding unique index on login to users, to catch the duplicates created when race conditions get around Rails validations.

Added model spec for it.

Adding a JavaScript function to prevent double submitting for that form, for users with JS enabled.

All features tagged @users are passing, so are the user specs.
