#238660 by hunmonk: Allow user admins to re-send validation e-mail. thanks to manoloka for sponsoring the work on this patch.

#239571 by hunmonk: fix broken mailing functionality. Resend validation email code is now properly updated to 6.x, logintoboggan_mail() was not using user saved mail subjects/bodies.

#204383 by hunmonk: User can register with email address. cleaned up validation code of duplicate username/email for the case where login with email is enabled. ripped out some duplicate code.

#215999 by hunmonk: Login on Access Denied resets itself when module listing page is submitted and there is a module dependency for logintoboggan. broke this check out into a FAPI validation function, and added a check to see if the module checkbox is disabled.

clean up validation problems with users changing their username/email to another user's username/email when login w/ email is enabled.

#204600 by hunmonk: theme_lt_username_title can not be overwritten in template.php. replace all hardcoded theme calls with proper calls to theme().

#204383 by hunmonk: User can register with email address -- doc error. removed faulty doc -- users have always been able to register w/ an email address for a username. tightened check for usernames that are already taken as email addresses by another user.

#198551 by hunmonk: User registration guidelines not on top of registration form. properly re-weight the help text.

#158027 by hunmonk: Login using email address only (alter display via theming). also prevent attributes from being clobbered in the user login form, and some code comment cleanup.

#196553 by hunmonk: LoginToboggan interferes with other modules altering registration form. manually place the registration submit function at the beginning of the submit handlers.

added auto-delete functionality for unvalidated users. a time interval can be set, and users still in the pre-auth role will be automatically purged from the system after the interval, if they are still in the pre-auth role. useful for cleaning up spambot registrations.

#57623 by hunmonk. Bring back set password only option. Add optional 'Immediate login' checkbox to logintoboggan settings page -- user is only logged in automatically if this is enabled.

updated email functionality for 6.x. cleaned up and clarified user help. fix notice. the module has been tested pretty thoroughly, and seems to work w/o problems on 6.x

no validation messages or db operations are necessary when the pre-auth role is set to the auth user.
