TrayButton in TitleBar

This has kept me occupied for a couple weeks. Most of what is in here I learned to use while writing it. I think I have thought of everything, but maybe not. The button draws itself in the correct system colours, it sizes and positions itself according to system settings. I have noticed that the TrayMenu does not react properly in the development environment, it does behave itself once compiled though. Also, when compiled, the Tooltip does not work until after you have restored the App from the system tray, but it works ok in the development environment. I don't know why this is, maybe someone could explain it for me.
