Allow to configure the available menu entries

[csware]

Is your feature request related to a problem? Please describe.
The menu of the photo app contains menu options for "faces" and "maps" - even when the apps are not installed (or I as a admin never want to install these).

Describe the solution you'd like
Automatically hide the options when the apps are not installed or make it configurable to hide these entries.

They are hidden per #1155 and #343 if the apps aren't installed, but there is an exception: if you're logged in as an administrator. I'm not sure why that exception is made.
