simplified UI for GSH templates (Security and "return to full UI" feature request)

I think the use of the of a GSH Template 'simplified UI' should be possible by users who are not generally allowed to use the UI. ( AKA: not in the 'Grouper UI access' group) Instead the GSH templates 'Security run type' config should fully control who can and can not use that GSH's 'simplified UI'.

Also I think the GSH template should support a "return to the full UI" link on the 'simplified UI' for those users who can use the full UI. ( AKA: members of the 'Grouper UI access' group) WHEN the GSH template allows the link to be show in the simplified UI. ( a new config setting in the GSH template setup.)
