* 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()
* 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)
* 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
* missing exports for new classes
* public non virtual convertToQString, propertyByIndex
* removed left-over of watchdog
* virtual destructor for avionicsbase.h
* improved formatting of aircraft views
* extended settings for render restrictions (such as max. aircraft, max range ...)
* connected new signal / slots in runtime
* Doxygen / formatting
* logical / physical add/remote member functions in drivers, renamed functions
* added access to snapshot
* snapshot generation in analyzer
* snapshot handling in driver
* moved simulator base class in own files (.h/.cpp)
* added functions as required to context
* added snapshot class
* added snapshot in analyzer, signal for new snapshot
* made all provider signals available in CSimulator
* added finders in CSimulatedAircraftList
* moved COwnAircraftProviderDummy into own file
* set infobar status correctly when GUI connects after the core has been started
* more detailed information in information statusbar
* allow to obtain currently connected server in network context
* made many network vatlib slots normal member functions
* fixed rendered aircraft flag setting in FSX driver
(similar to remote aircraft provider)
* removed references
* made own aircraft context thread safe (reg. own aircrat data)
* removed the read only versions of the provider
* adjusted consuming methods
* renamed some functions ("ownAircraft...") to avoid ambiguity (with remote aircraft)
