* changed ***FileIsUnparsed in FileRegister to disregard files that are currently parsing.
* made Cach more generic by adding the option of providing a custom hasher
* added sql index for component_access
* improved policy for expanded code files
* reduced amount of initially expanded code files
* faster DummyEdge creation
* faster DummyNode search by token id
* switched GraphController DummyNodes and DummyEdges to shared_ptr for memory safety
* fixed crash when snippet has no code.
* fixed crash when saving a filenode with special characters in its name
* fixed crash when aborting the parsing
* added option to define the amount of parallel indexers in the appsettings
* fixed unparsed files query in ASTVisitor
* fixed: to update a node's type in the storage the node does not have to be defined anymore
* modified the TaskParseCxx to be able to run multiple times in parallel
* made FileRegister threadsafe and changed a lot of its mechanisms
* added TaskGroupParallel that runs all children in parallel
* added TaskParseWrapper that acts as a decorator to execute some code before and after parsing.
* implemented task setup in project with 4 parsing threads
* removed SimpleTask as it was only used as interface for the LambdaTask
* renamed Storage to PersistentStorage
* added Storage as baseclass that implements data injection
* cleaned ParserClient interface
* added default constructors for storage types
* cleaned SqlteStorage by implementing the private getAll methods as template specializations
* added CXX flags to CMakeLists (this is needed for sqlite with visual studio)
* removed TestStorage.h/.cpp since these files were not used anymore.
* fulltextsearch enabled in sqlite
* fulltextsearch start search with @
* codeview performance improved
* strip sRGB profile from png files to get rid of libpng warning at runtime
* fixed size policies of codeview elements to prevent the codeview from having a global scrollbar
* fixed crash in sorting of search results
* removed debug log when panning a codesnippet
* updated color scheme highlight colors
* fixed highlight color resetting
* prevent project file being save with no changes
* fixed MessageListener crash due to alive flag being set too late
* new edit project icon
* fixed deleted project could still be selected in the recent project menu
* fixed project file not loaded when declining for reload
* fixed main in tutorial description not clickable
* fixed clang warnings
* fixed commands not showing up in autocompletion
* fixed classes were expanded when activating aggregation
* fixed crash when messagelisteners tried to unregister after messagequeue was destructed
* FilePath::relativeTo(...) did not return correct results for non-canonical paths (for a base path containing "/foo/.." it would prepend "../" two times instead of omitting it).
* fixed bug where panning stopped when hovering the line number area in the code view.
* when relasing the mouse button on a clickable code location after panning the location is not activated.
