Allow option to not script logins when generating script and also add check for existing users to avoid errors
I was trying to create a copy of the development DB schema into local server. I got errors and warnings. The error I got was in the section of code that created the login and then attempted to create a user (myself). I didn't sent this error as it contained some confidential info. There also needs to be a way to remove things like login names from the generated email.
