- 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
