* refactored to member initialization
* adjusted asserts
* adjusted isXXObject methods
* changed create method for ContextNetwork to support empty context
* empty status message used as return value in empty context
* discussion: https://dev.vatsim-germany.org/boards/22/topics/2027?r=2040#message-2040
* fixed bug with ATC station component, wrong signals for booked stations
* booked stations loading to frequently (for each minor change such as online), changed to timestamp based concept
* update booked stations with receiving ATIS/voiceroom to online
* CDigestSignal class: new class and methods for collecting signals, avoiding too many signals - one of the cures for the performance issues
* fixed bug found during testing, missing start for timers when connecting to network
* some improved comments and information
* QMetaObject::invokeMethod in tool.cpp as thread safe invocation
* common base class for threaded readers
* removed event class, using QMetaObject::invoke instead for forcing calls in main event loop
* stop methods for readers, as used for graceful shutdown (preparing for thread safe destruction of objects)
* graceful shutdown for network context
* calls in tool now via inkoke for thread safety (only thread safe methods called directly)
* load flight plan method
* removed public getOwnAircraft method refs #242 -> own aircraft context
* Improved handling of selected stations
* Some debug info for #refs 255, will be removed when solved
* asserts for relaySignals
* relay "message" in connection status changed
* bug in status message
* bug in saving settings
refs #198 refs #199 refs #207 refs #209
* friend CRuntime on top
* fixed some public constructors (made protected)
* Also made registerWithDBus protected
* Fixed some copy/paste issues in getIContextXXX
* Reordered private/public sections
* removed usingLocalObjects() now in CContext
* removed getRuntime() now in CContext
* Constructors no longer public, context can only be obtained via runtime object
* runtime class is friend class
In #85 the voice context will be renamed to audio context, so the CValueObject classes will be renamed to namespace Audio too.
As #140 changes many CValueClasses, this crossover change is done in the same unit of work.
* Timer for bookings removed
* Adjusted context slots for reader class
* Consolidation of ATC online and ATC booked in booking receiver slot (CContextNetwork::psReceivedBookings)
as these data are not actively pushed from network when changing
* timer in network context
* update methods, one specific method for ATIS as this can also be manually re-read(from GUI)
* readAtcBookingsFromSource() const; to non const, it changes data in the context
* better adjusting of update time for bookings
* No updates if URL is empty, checked.
