add another bug to the list.
Add ignore for latest QtCreator.
Fix issue when clicking tray menu.

The only way to bring up the menu on OS X was
also bringing up the main window. Very annoying,
so this stops the main window from being raised.

Also add some TODOs.
Add ability to autostart.
add a new (big) bug to TODO.txt.
Fix CMake build

- Add CMake macro and use it to link Carbon and Cocoa
- Use "APPLE" CMake var instead of "Q_WS_MAC"
- Add *.mm files to the CMake source list
