QNX: Add support for attaching to a running application
This adds a new menu item to the Debug -> Start Debugging menu, which shows a processes dialog for the user, listing the processes on the selected device. Clicking Attach to Application launches pdebug on the device and then starts the gdb engine to attach to the selected process. This adds a DeviceTypeKitChooser class to ProjectExplorer, to only have the KitChooser show kits configured for a specific device type.
