* threaded reader were normal members causing a crash when those were moved in their own thread
* we need own event processing for unit test
* Network request needs to be generated in main thread
* don`t shutdown readers on QCoreApplication::aboutToQuit, let CApplication handle it
* use CApplication in unit test (as in real world)
Unrelated:
* access global setup via application
* a single base URL (shared), derived URLs by appended path
* simplified dir structure shared with sub directories
* renamed functions
* automatically synchronize setup with DB when initialized
* trigger download info loading when setup is completed
* allow to automatically read after setup data have been synchronized
* read DB data when setup has been loaded
* allow to reload from threaded reader
* improved handling (log messages, skip reading) when data are not available
