[horde] Activesync on Android mail sync

Conversation support is spotty, at best, with our ActiveSync  
implementation. There are a few reasons for this, some of which are  
due to the fact that Exchange has access to specific MAPI properties  
that allow it to detect related emails, and to parse out the unique  
parts of each email (instead of duplicating the quoted text in each  
email). Some of it we could probably improve, but others are just not  
possible when using IMAP (as opposed to MAPI) as a mail store.

If you provide a sync log showing the conversation requests I can see  
what we can improve. I don't have any clients to test that truly  
support this - most just implement it client side (using only the  
emails available on the client, of course) similar to IMP's  
conversation view.
