Consider other locations when resolving IUs from updatesites
Currently the IULocation can only consider units from other locations if these are also of type IU location but other target types might be able to supply items in a way not know to the IULocation. This adds the necessary infrastructure to support this usecase by using the adapter pattern. Fix #207
