When generate menu, generated code reference all activity (for entity) even if doesn't exists
To do this, we could only check the existence of the various referenced files, but that would be ugly.
A good thing to do would be to an inter-bundle communication like this :
TACT-navigationmenu would ask the TACT-core what are the activities used in the navigation.
The TACT-core will ask himself and every other present bundle if they have any navigation activities available (by checking if their own files exist ?).
It will then send the Activity list back to the TACT-navigationmenu.
This method would be very practical and would resolve issue #3503 as well.
