Here is t2.login and layout.html changed in t3 so that:
1. when there is a failed login, it keeps the email in the email field
and puts the cursor in the password field
2. if it is an invalid email address it puts the cursor at the end of
the email address so it can be fixed
3. theirs IS a better way to do this - i just don't know how :)
4. i did this cuz retyping email in username fields after login
failure bugs me ;)
