* plugin changes, mapper/parser will be stopped.
make sure worker is properly shutdown
* restarted FS/FSX. Allow to reset mapper/parser data from store
* 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
* disabled sets distance and max.aircraft to 0
* fixed changed snapshot detection
* added rendering enabled to signal, only one function to decide (instead of duplicated logic)
One constructor will accept a QString argument directly and use
it as the originator name. The other one accepting the a pointer
to QObject will use QObject's objectName.
* fixed isCurrentThreadCreatingThread and renamed to isCurrentThreadObjectThread (this check was never working), added 2 more thread checks
* changed remove aircraft function to return number of returned aircraft (like with the containers this allows to avoid unnecessary signals)
* removed unused function ps_recalculateRenderedAircraft() / SimulatorCommon
* using Queued airspaceAircraftSnapshot signal for binding (functor connect does not provide connection type)
* extened ASSERTs to check threads
* simulator: initial situation function with return value (success?)
* simulator: avoid unneccessary copy and provide correct rendered flag in add aircraft function
* Redundant "simulatorStatusChanged" signal in proxy
* invokeMethod for timer
* removed redundant this->buildNavigator(1)
* Shortcut in GUI
* comment in variant
* added unload function to disconnect signals / slots and simulator
* changed remote provider to return signal/slot connections to manually disconnect functor connects
* flag so pause can freeze or continue AI aircraft
* slightly changed unload behaviour in simulator context
Remark: Tested for FSX only
Solves #424 for FSX
