SAK-1466 and SAK-1559.
Some sakai installations urgently need the ability to navigate upwards in Resources and/or in the file-picker. And others don't want that at all.
It should be possible to set a property for the Resources tool that allows upward navigation in the tool. The default should be that it does not allow upward navigation.
It should be possible to set an attribute in state as part of enabling invocation of the file-picker by a tool that allows upward navigation if that makes sense for the tool. If that attribute is not set, the default should that upward navigation is not enabled.
