New User wizard not handling Users with a dash in correctly and Copy User Preferences wizard now warns if a range of Users is specified

When copying User preferences via the 'Copy Settings' page in the New User wizard, if the new User 's User Id contained a dash, this could overwrite an entire range of Users' preferences

When using the Copy User Preferences wizard to copy settings from one User to one or more other Users, clicking 'Next' on the Destination Users page will now show a confirmation if the range of Users selected contains a range or wildcard entry, e.g., an unquoted User Id containing either a dash, asterisk or question mark.
