Further work on detecting message removal when folder first selected: #3805

Browse source 
Needed to rethink storage strategies as I researched this and realized that a true scarce database -- where the database is sparsely populated both in columns and rows -- is not feasible due to IMAP's UID rules.  The strategy now means that the database rows are contiguous from the highest (newest) message to the oldest *requested by the user*.  This is a better situation than having to download the UID for the entire folder.
