* 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)
Some interesting results:
* Minor simplification of PQ converters and unit ctors; may not seem like much, but I think it enables possible future simplifications of a similar kind.
* CMeasurementPrefix is gone, no longer needed. Now prefixes are applied at the template stage.
* Apart from that, PQs public API is unchanged.
* Discovered that ft/s^2 conversion factor was wrong: fixed.
* Default unit is more clearly stated in one place, not restated in many different places, and is not always the SI unit
* Converter strategy pattern in CMeasurementUnit, covering linear, affine, and different kinds of sexagesimal units
* General reorganization of CMeasurementUnit construction and CPhysicalQuantity methods, not removing any behvaiour
* Move duplicated method unitFromSymbol from derived classes into base class CMeasurementUnit
* For DBus, CPhysicalQuantity marshals both in its own unit and in the default unit
