Subject: - Rewritten messages caching (merged devel-mcache branch):   Indexes
 are stored in a separate table, so there's no need to store all messages in a
 folder   Added threads data caching   Flags are stored separately, so flag
 change doesn't cause DELETE+INSERT, just UPDATE - Partial QRESYNC support -
 Improved FETCH response handling - Improvements in response tokenization
 method
