* removed CacheUntilNewer
* did not really work and had some problems
* cache timestamp not really a good value to compare with
* too slow with remote file
* simulator info for FS family / as set
* fixed synchronized typo
* info string for caches
* getter for cached models from the loaders
* get all FS family models (FSX/P3D/FS9) from list
* callback function to data consolidation (so I can refer to consolidation in BlackCore)
* use status message in parser
* avoid duplicate keys (WOAI has ambiguous model strings which are to be excluded)
* call of non-virtual function in ctor
* use getCopy
* return number of merged models
* change current simulator in model set loader (fixes infinite loop: change data -> signal -> change data).
* removed from component cache
* kept renamed component caches as stubs for later usage
refs #646, removed gui state cache as it causes build issues on Jenkins
(idea was to keep the classes as stubs for later usage)

* CPixmap support for loading pixmap from file
* Access to model of model set loader by model string
* icon path as member of CAircraftModel
* moved caches to blackmisc
* used CModelCaches in loader
* applied changes in simulator specific loader classes
* renamed find function to findFirstByModelStringOrDefault
* made merge function static so it can be used elsewhere
