[MlMt] Mailbox count = Recent

[Randall Gellens]

When the displayed count for a mailbox is "Recent," what does MM count?

I would like to suggest that there be an option for the count to be 
"Unread messages that have arrived in the past [count] [unit]" where 
count and unit are settings (global or per-account or per-mailbox).  For 
example, setting count to 7 and unit to days would count unread messages 
that arrived in the past week.
