Authors should not see "Document Types" section.

In the browse tree/ section tree when logging in as authors with limited authorization you should not see the "Document Types" in the configuration. Because this is a seperate plugin (each element in the section tree, such as Document Types, are seperate plugins), By setting an authorization rule you can hide the plugin and when not accessible or not there when the element will simply not be skipped. Thus this would require no implementation in the SectionTreePlugin, but only configuration.

However, the patch to be uploaded in a moment containing this authorzation restriction does not work as expected. The rule itself works, but when used, to layout of even the dashboard is totally messed up. This baffels me, especially when deleting the plugin (keeping the autorization rule), actually has the required result.
