refs #219, load flight plan

* 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)
