* each stream type now uses its own max connection value
  for mysql pooling

* async callbacks are now done in a way that only allows
  a thread to be 'finished' in async after all of its posts
  are imported; the same goes for the boards-threads relationship.

* board and thread imports are no longer done in parallel

  * This is done to prevent the deadlock situation in which
    threads/boards take up all the mysql pool connections
    (in conjunction with the shared mysql connections limit)

* added log file capabilities
extract imports to variables and fix async.series call
optional split for user and forum import
