data: Fixes and features for loading Coati into Coati

This change facilitates loading Coati into Coati:
* removed error logs for TokenComponent setting
* fixed edge checks regarding template stuff
* separated CommonSettings to be inherited by Project- and ApplicationSettings for common settings
* pluralized SourcePaths setting in xml to allow for loading multiple directories and single files
* added CompilerFlags section to settings
* passing Compiler arguments to Parser via struct Parser::Arguments
* setting -isystem for all header search paths to avoid distinction between "" and <> headers
* parsing all headers from the SourcePaths, even the ones that are not included
* fixed parsing time measurement and display
* added utility.h file for general utility functionality
