(applied after 1st performance fix for cache was ready)
* utility functions to detect if only caches are used
* renamed some functions
* renamed some db flags and added new ones
* New hint flag: DB data for the client will no longer be web loaded but fetched from cache whenever possible
* No public constructors for the 2 classes
* adjusted main
* IATA code for airlines
* selection for airline designator returns list not single object
* misc finder functions for airline list
* formatting, use MS override Doxygen style
* only call this->abandonAndWait() when not in main thread (also slack discussion MS/KB)
* make sure web data service start to read even if setup reader signal was missed
* add timestamp to setupreader to detect "recently read" in case signal is missed
* fixed in launcher so reloading works (this also uses fixed URL list)
* signal for version synchronized
* removed setupreader.h where possible -> less compile dependencies
* removed redundant logging
* removed unused cleanup override
* connect &QCoreApplication::aboutToQuit in threaded reader
* 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
* URLs no longer have to be passed
* watchdog for DB readers to check DB status
In same step:
* fixed some log messages and comments
* allow to self signed SSL certificates
* adjusted namespace for CNetworkUtils (now in network)
* Will allow to load data if DB is not accessible / available
* Also allows to save, so a special set can be saved for testing/forensic.
* fixed status bar, as received data no longer means DB is alive
* renamed to connectDataReadSignal
* removed unused individual signals, e.g. vatsimMetarsRead -> replace by data read signal + entity flag
* added data in METAR class (kept there, not in airspace monitor) -> reader aware
* renamed files without "_"
* added flags
* integrated URL into global reader settings
* added new parameter for connectVatsimDataSignals
* removed unused setting in settings / network.h
* flags for readers (which reader is reading specific entities etc.)
* web data services: bundling multiple readers (webdataservices) and implementing IWebDataReaderProvider
* readers now able to read single entities
