Filter: Allow integers in operations on clists

Browse Source 
The clists are internally implemented as integer lists. We currently
allow pair values (communities in community list) and quad values
(cluster ids in cluster lists) for add/del/member/filter operations
on clists. Allow also generic integers, so it can be used as a generic
integer list.
