When creating a new wiki based on a template the wizard settings are ignored

For example if your template wiki has "global users only" and you create a new wiki and select "global and local users", you'll get a wiki with "global users only", which is not what is expected by the user.

We have 2 choices:

• Either grey out and make read only the choices that won't have any effect
• Or (better IMO), apply the settings after the copy
