A patch from Pierre Smits for "User with update permission can't access screens in content application" https://issues.apache.org/jira/browse/OFBIZ-5676

When a user has security permission 'CONTENTMGR_UPDATE' he should be able to access various screens in the content application, but he can't.

This applies to screens associated to menu-items:
Content
DataSource
Content Setup
DataResource Setup
Template
CMS
