* Implemented new format splitting user, version, and usage period into separate lines
* Refactored all classes: License, LicenseGenerator, LicenseChecker
* Removed redundant license check hash from ApplicationSettings, don't generate, store and check it anymore
* Moved license checking and encoding logic to LicenseChecker
* Moved default for license generation to main.cpp
* Refactored license checking logic in whole app, removed involved message types
* Added LicenseCheckerTestSuite for checking all legacy and current license types
* Generate new license type lifelong
* Rerun header path detection when only cxx header path is present after update in migration
* Check if path exists in header and framework path detection on mac/linux
* Always add compiler header path when prefilling on first start, regardless of successful detection
* Show compiler header path in path list box on top and readonly
* Prepend compiler header path on Windows in system header path compiler flags, append otherwise
* Show warning when saving ApplicationSettings if compiler header path is not in global include paths
* Show warning when saving ApplicationSettings if there is another path containing compiler headers
* pass file language from storage to code view
* load syntax highlighting rules files from install directory "syntax_highlighting_rules"
* files must be named <language_identifier>.rules to make syntax highlighting work
* Added new Source Group type SourceGroupCustomCommand to UI and ProjectSettings
* The Source Group executes a specified command on every source file
* The variables $SOURCE_PATH, $PROJECT_PATH, $DB_PATH, $STORAGE_VERSION can be passed
* The commands are executed after all other source groups finished indexing
* The command is executed with working directory set to project directory
* Errors during command execution are shown as status update and in the Status View
* SourceGroupCustomCommand cannot be partially cleared, when one file needs clearing the project must be fully re-indexed
* Enabled errors table during indexing
* Store intermediate errors in StorageCache
* Open tab for errors if no tab yet
* "Show errors" for file disabled during indexing
* Hide indexing dialogs with ESC instead of stopping indexing
* Fixed indexing can be interrupted when dialog hidden
* Clear intermediate storages when interrupting
* Abort waiting for less queued storages when indexing interrupted
* Don't index another file when indexing was already interrupted
* Moved indexing interrupted progress dialog to TaskBuildIndex
* Use MessageIndexingInterrupted instead of MessageInterruptTasks
