#863890 by hunmonk: user_register value default has changed, contants for its values.  thanks to rfay for the tipoff.

hide the auth user checkbox on the user edit screen if the user is in the pre-auth role -- reduces UI confusion.

#765994 by hunmonk: Non-authenticated role is hidden in user profile form even when 'Set password' is unchecked

value -> markup. refactor check for a manual removal of the pre-auth role by the admin -- use a hidden form field instead. fix logic for password description. add a missing user message for registration when the pre-auth role is the auth user. fix broken query placeholders. remove unnecessary query that erroneously updated a user's login time when an admin validated their account. fix broken call to drupal_goto. fix up redirect array. use core's user mail functionality for resending validation emails. fix broken mail_alter implementation for admin validation emails.

refactor mailing code to use user module's functions, tokens, and hook_mail_alter. make sure anonymous user can't access revalidation link menu callback. remove unneeded security check from registration function.

login successful message now contains username.  logged in block now uses theme_username on username.  update theme functions to work for 7.x.  clean up and refactor the access denied/login form functionality.  use a custom user admin permission js file when the pre-auth role is not the auth user -- allows pre-auth role to have lower permissions than auth role.

by hunmonk: add an 'Override destination paramter' setting, enabled by default. this gives admins the option to allow LT to force it's redirect paths over a passed destination parameter. related to solving #604492

#604508 by hunmonk: 'Use two e-mail fields on registration form' setting breaks OpenID registrations. this fixes the LT-related problem, but the openid registration process itself may still be broken -- see #216101

#232467 by mfer, benroot, hunmonk: OpenID logins broken when 'Allow users to login using their e-mail address' setting is enabled.

#492486 by mikehostetler: Array merge of user_register_submit function squashes pre-defined user_register_submit functions.
