Temp hack to merge all custom fields of subcontacts into the metacontact
Temp hack to merge all custom fields of subcontacts into the metacontact

As the presence is set as custom KABC::Addressee field, we simply merge
all the custom fields from the child contacts into the metacontact so we
can have at least some presence for now.

The presence needs proper handling (selecting the most online presence
from the subcontacts etc).
