Bulk add users and auto-create personal blogs as required for each user
Allow blog admins to bulk add users from the LDAP directory to their blog. If any of those users do not already have WordPress accounts, create a new personal blog for them in addition to adding them to the blog in question.
Honor the option of create new blog for user in bulk adds. Right now, this feature only works when adding users one at a time, or when bulk adding, will only work for the first user in the bulk add list.
