Various Bugfixes and cleanups

* remove debug statements from SmDirWatcher
* Don't crash on parentDir when current Dir is already deleted
* Fix PicFilesModel MappingQuery. It needlessly referenced the table
pics in FROM causing an expensive full table scan!
* Fix findRecursive in PicFilesModel: Stupid typo!
* Give SmDirWatcher a separate DB-Connection. One Thread, one Connection
* Remove several includes

This should have been 6 commits, but that's how debugging works :(
