* Flattened sourcegroupsettings class hierarchy by moving cross compilation options to own base class
* QtProjectWizzardContentFlags constructor required correct settings object to reduce the need for type casting
* QtProjectWizzardContentPath constructors required correct settings objects
* moved SourcePaths from SourceGroupSettingsJava to SourceGroupSettingsJavaEmpty because they are not required for Gradle and Maven projects
* removed classpath from maven and gradle source group settings
* reuse code of SourceGroup for "show source files" in wizard
* also changed xml elements in sourcegroup settings that specify the used language standard, so that one sourcegroup can maintain multiple language standards
* added migration and migrated sample projects
* added classes for loading a Sonargraph project
* added Sonargraph options to project setup wizard
* added test for generating indexer commands from Sonargraph modules
* fixed sqlite storage crashing in constructor when parent directory of provided path does not exist
* removed unused FileRegister from Java indexing
* removed unused info from IndexerCommandJava
* refactored loading and saving of SourceGroupSettings
* extracted sourcepaths settings to own class that can be re-used
* merged CDB wizard contentents for source file and indexed paths
* unified wizard content for sonargraph project path
* removed include filters from default source groups
* extracted generation of RefreshInfo from Project to RefreshInfoGenerator
* added tests for RefreshInfoGenerator
* added language and standard selection to sonargraph project setup
* added auto-detection for indexed header paths of sonargraph cmake json modules
* Sonargraph::Project can enable/disable support for specific modules
* warn if sonargraph project contains no matching modules
* indexed headers can be detected from sonargraph project
* disable re-pre-filling of indexed header paths if these are empty when showing settings of a cdb sourgroup
* fixed indexed header path were not regarded when deciding if project settings have been updated
* prevented indexed header paths for CDB to be appended to compile command
* fixed exists check for relative paths in QtSelectPathsDialog
* indexed header paths will automatically be updated when a new compilation database is picked
* put nodes with bidirectional aggregations on the left
* layout aggregations either horizontal or vertical based on buckets
* exceed bucket height if only one element and vertical split
* fixed hiding nodes in sublayout showed empty spot
* fixed aggregation layout within group
* fixed moving of group did not resize view
* fixed edges behind group could not be hovered
* fixed overlapping lines in sublayout
* fixed use of correct column width in sublayout
* implemented using multithreaing for building the fulltext search index
* also: decreased ideal thread count by 1 to keep the machine responsive while indexing and building the index
* extend horizontal edges to origin column width
* leave horizontal gap in the middle of the left and right buckets for routing edges
* move left and right buckets vertically so that edges enter and leave horizontally
* removed third pivoting for graph edges, all edges enter and leave relative to the node center now
