* support for loading from datastore
* improved timestamp handling
* new color and country classes
* new attributes
* updates for missing parts in CUser
Also refs #351
* messages can be formatted with style sheet
* fixed: removed command from message
* added originator to command line
* msg parsing now in core
* using ITimestampBased for text messages and status messages
* allow to resize rows to content (view base)
* model / views for text messages
* removed old qt stylesheets
* using split by callsign everywhere
* helper function to insert_front
* revised linear interpolator
* renamed to remoteAircraft
* renamed to container() in providers (gettters are usually copies)
Issues why changes did so long:
* insert in list is not adding in front, but same as push_back (that was confusing)
* naming of values before/after in interpolator was ambigious
* QMap keeps values sorted by key, not arbitrarily
* consolidated ICoordinateGeodetic (e.g. fixed nested properties)
* shifted common functionality for objects/containers with callsign into interface
* shifted common functionality for objects/containers with geo position into interface
* shifted common functionality for objects/containers with timestamp into interface
* updated corresponding value objects / specialized lists
* adjusted all places where renamed functions are used
