Refactoring: Merge AddMemberBox and AddIncludedGroupBox

Merge AddMemberBox and AddIncludedGroupBox into one class since most
of the coding is identical.

This refactoring is a preparation for allowing groups being added as
reviewers for a change. Otherwise to implement this feature it would
be needed to introduce a third class AddAccountOrAccountGroupBox
which would again be almost identical in coding. The idea is to just
have one class which can be used for all three cases.
