Refactorized cmdlineparser.cpp: 

- Added const char* overload for PrintMessage()
- Call Path::removeQuotationMarks() before any other path formatting functions
- Fixed --help output on terminal outputs with 80 columns
- Hide -l option on systems where it does not do anything
- Added pre-check for "-" at the beginning to distinguish between options and files early
