Add a toggle for Subitems to location-view

[WhiteSockedDancer]

What is the problem you are trying to solve with this feature?

My locations get quite filled with subitems of other items in location-views.

What is the solution you are proposing?

Add a toggle (that is probably saved in cookies/profile) to disable Subitems in location views.

What alternatives have you considered?

• allow items that have a parent item to not have a location (acceptable)
• remove subitems completly from location view (not preferred)

If you merge locations and items into one object type this issue should be gone, since subitems would not have another location beside its parent object.
