The GC Icon in contacts was originally put there by Datapath for when planning on having only an "All Contacts" list, to distinguish what contact list each was from. With the combo box saying what contact list you are in, it seemed redundant without an "All Contacts" feature.

I intended "None" as a universal fallback. I was thinking that since not all setups will have evolution support and not every user will want the performance hit if they accidentally click "Contacts" and it loads their GC Contacts, we can fallback to "None".

I didn't go with only an "All" because not all would like the performance hit of GC Contacts. I have not yet done an optional "All" out of laziness and the dirtiness in knowing it would be imperfect in merging the contact lists. Adding this would mean I'd probably have to add back in the icons and then provide icons for the other modes. Since I'm e lazy, to avoid svn conflicts I'll wait till brontide commits in case his threading/performance work might have touched those areas
