* also added current page count (e.g. 1/3) to project setup
* moved the code for copying a source group to the settings classes so that the wizzard doesn't need to know which source groups may be there anymore.
* replace path to local compiler headers with packaged ones in include path detection
* added app settings migration to replace local compiler header path with path to packaged headers
* 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 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
* split QtDirectoryListBox and QtStringListBox
* renamed QtDirectoryListBox to QtPathListBox
* extracted QtListItemWidget class to own file
* renamed QtListItemWidget to QtListBoxItem
* added SelectionPolicyType to QtPathListBox to allow for specifying if selecting files, directories or both should be allowed.
* removed header paths from VS Project setup message since VS doesn't send these anymore
* implemented using wstring in IDE communication
* fixed retrieving filepaths from QtDirectoryListbox that contain special characters
* use wstring for source extensions
* added special character as file extension to FileManagerTestSuite
* used wstring in FilePath constructor where easily possible
* added FilePath concatenate method that accepts string parameter
