Add "only contained" attribute to unit types

[ibboard]

Currently, all units show up at the top level for the categories they are in. This works for now, but when we get the containership UI in place then we'll have units (e.g. champions) that are contained and don't have an existence in their own right. For these units we need to declare their unit type as "only contained".

This attribute should:

• Stop units showing in a "get unit types for category" call
• Be ignored for a "get all unit types for category" call
• Be loaded from data files
• Make the unit be deleted when its parent is deleted

Re #359: Add "only contained" attribute to unit types

• Make sure we add and remove from the parent unit appropriately
• Make sure that setting the unit's parent to null removes it from the parent

Re #359: Add "only contained" attribute to unit types

• Make sure remove handles sub-units as well

Note: warning the user that the unit has sub-units rather than just removing them is left to the UI

Should all be handled now. Leaving the ticket open until user testing is done.
