Refactor, fixes and maximized option for title tab (#40)

* move definitions of switcher structs to separate files

* remove useless comment

* cleanup and silence warnings

* add generic switch

* removed delay on main thread startup as it served no purpose

* clean up ultility.hpp

* do not save switchStr to file as it could cause issues when scenes are renamed

* rename sceneRoundTrip to sceneSequence

* add option to switch if window is maximized to title tab
