Added Auto Backup DB Ability

v.1.7b Beta - Created an Automatic Backup aupm.db from Manual Backup
upm.db on application exit
--Restore still from Manual Backup file upm.db
--If want to restore automatic backup, must rename aupm.db --> upm.db
from root of sdCard
(This makes good practice to do manual backups in the first place, but
leaves a safety net
for just in case i.e. database corruption)
