* 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
Previously the metar source used to be the FSD connection. Since
all METARs are also available via a webservice, use this source
instead. This allows to retrieve and use METARs even if we are
not connected.
* the reader will be used in context, but can also be used standalone (ie mapping GUI) GUI
* adjustments in context/airspace as required
** for web reader
** livery
* base class for database based reading (via JSON/web)
* model data reader for models
* simulator common, many members now private (info -> read only)
* renamed printDirectPlayError -> logDirectPlayError
* (re)added ASSERT for FS9
* removed parent from listener (with parent no moveToThread)
* removed QFuture / QConcurrent as we have agreed to do
* unloading a plugin no longer automatically restarts all listeners
this allows a user to set one particualar simulator in the GUI and ony wait for that
* stop listener from own signal
* only 2 public interface functions start/stopSimulatorPlugin
* internal functions like starting the listeners private
* removed loading from settings, it does not make any sense as auto will find the running sim
* only 2 central functions in impl: un/loadSimulatorPlugin - rest is handled automatically from there
* graceful shutdown when runtime goes down
* utility function getSimulatorStatusEnum()
