This also means moving Mixin::Icon from CContainerBase one step down the inheritance hierarchy
to resolve what would otherwise have been a circular include dependency.
The following issues were fixed
* Fixed wrong/missing namespaces
* Fixed obvious typos in documentation
* Documentation not in sync with source code
refs #544
* support for loading from datastore
* improved timestamp handling
* new color and country classes
* new attributes
* updates for missing parts in CUser
* CAircraftMappings -> will be replace by CAircraftModel
* CAircraftIcaoData aircraft ICAO data -> aircraft/airline ICAO code and livery
* CAircraft class no longer to be used, but CSimulatedAircraft
* removed corresponding GUI model classes / filters
* common base class for DB based classes
* common base class for DB based containers
* Livery, distributor value class
* adjusted value classes to livery
* utility functions for DB values (blackmisc free functions)
* register new objects with metadata system
One constructor will accept a QString argument directly and use
it as the originator name. The other one accepting the a pointer
to QObject will use QObject's objectName.
* DBus mixins moved to dbus.h
* Json mixins moved to json.h
* Icon mixin moved to icon.h
* Comparison mixins moved to compare.h
* Hash and string mixins moved to blackmiscfreefunctions.h
* Index mixin moved to propertyindexvariantmap.h
* MetaType mixins moved to variant.h
* registerMetaValueType moved to variant.h
* valueobject_private.h renamed to variant_private.h
refs #404, and discussion https://dev.vatsim-germany.org/issues/404#note-8
* Changed CSimulatorSetup to use CNameVariantPairList as data. The old version was an hack and had to go, CNameVariantPairList would allow complex types in the future and can be already shown in the GUI.
* CNameVariantPairList was improved slightly in the same step
* Functions to get CSimulatorSetup from driver / context
* Removed CSimulatorSetup data from CSimulatorPluginInfo
* Involves rearranging some header includes to break cyclic include dependencies,
* Adding a new, simple base class CEmpty,
* Removing any remaining polymorphic uses of CValueObject with templates,
* Adding a new trait for use with enable_if to restrict templates to work only with value objects,
* Replacing the polymorphic/runtime multimethod-based compare functions with static/compile-time compare functions.
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
* support of property index
* used support classes BlackMisc::ITimestampBased, ITimestampObjectList and ICallsignObjectList
* fixed some issues in related aircraft situation class in same step
* 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
* Start index 10 instead 0 for CValueObject (easier to detect bugs)
* Fixed wrong indexes
* Asserts in CPropertyIndex
* Used Icon instead of QPixpmap with indexes, icons are sortable and have a tooltip
* Removed redundant toQVariant methods
* renamed fromQVariant to convertFromQVariant, the "from" methods imply the object is changed (fromJson, fromString ..)
* implemented fromQVariant - changing the object by QVariant
* moved toQVariant into PQ template
* free function setFromQVariant
