ALL: Added saveSetup() and restoreSetup(). Fixed / Improved watchdog …

…(especially in Linux). Fixed / improved setPosition() method

LINUX: Added ewmhlib as separate module. Fixed watchdog (freezing randomly invoking screen_resources and get_output_info), fixed workarea crash (some apps/environments do not set it), improved to work almost fine in Manjaro/KDE, avoid crashing in Wayland for "fake" :1 display (though module won't likely work)
WIN32: Fixed dev.StateFlags returning weird values for multi-monitor. Fixed GetAwarenessFromDpiAwarenessContext not supported on Windows Server
MACOS: Replaced display-manager-lib by other alternatives which seem to work in several macOS versions. Added setScale() method (using a workaround). Added wakeup feature to turnOn() method
