Make Notepad++ invisible on startup while printing and unit-testing

The both flags -export=functionList & -quickPrint don't need Notepad++ GUI, so Notepad++ will start up invisiblely while one of these 2 flags is given. It doesn't prevent Notepad++ from being visible in the case of -export=functionList but this PR make unit-tests more bearable.
