Generic Fragment Layout was defined
Specific Laout Object wer integrated including all object specific handling
FragmentObjects can now be added to ListViews.
Possible clean solution would be to have a PagingAdapter for each object type.
From now on, it is possible for the API to retrieve only object which
are assigned to a specific game or only objects that are available or both.
This might (pretty sure it is) needed in the future
These functions return all items of a single kind.
We need to think of if we should handle more logic within sqlite
queries (eg. more specific like get all characters of this game) or if we would
like to handle this on apps side.
