* 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
* fixed issue with parsing, only default locale is used. Now user's local possible
* allow to load FP for other callsigns as well (voice capabilities)
* Improved handling of CTime, inclusive bug fixes and time formatting
* Max. lengths for FP fields as const value (so we can change it if required)
* Load FP from GUI component
* Samples for PQ classes
* Adjusted depending classes (e.g. client)
* Naming convention: "preset" only when disconnected, "send" only when connected, "set" both
* Every asynchronous pair is named as in "sendFooQuery" and "fooReplyReceived"
* Moved LoginMode from CNetworkVatlib constructor to INetwork::presetLoginMode
* Callsign and ICAO codes can only be changed when disconnected, so have their own "preset" methods
** Callsign and ICAO parts of setOwnAircraft are therefore ignored
** CUser part of setOwnAircraft is ignored, in favour of the CUser part of presetServer
* CNetworkVatlib takes care of reconstructing m_net if the LoginMode is changed
* INetwork setOwnAircraft slots
* ATIS received shimlib callback triggers separate VoiceRoom and LogoffTime signals
* INetwork statusMessage signal emitted in response to shimlib errors
* INetwork::ConnectionStatus added a DisconnectedError value and toString conversion
* INetwork::isConnected method
* Argument in CNetworkVatlib constructor to enable stealth or observer mode
* Update CLI sample, tests, and CContextNetwork accordingly
