function user_update_7017

Update email templates to use new tokens.

This function upgrades customized email templates from the old !token format to the new core tokens format. Additionally, in Drupal 7 we no longer e-mail plain text passwords to users, and there is no token for a plain text password in the new token system. Therefore, it also modifies any saved templates using the old '!password' token such that the token is removed, and displays a warning to users that they may need to go and modify the wording of their templates.
