Moved CO2 Menu from Xtra to Hardware: The first CO2 sensor menu implementation was placed within the Xtra menu. In the new version the CO2 options may be accessed using the sensor overview menu of the Hardware page. With this change it is no longer necessary to take care for compile switches in the menus because the menu will only be shown if a CO2 sensor is detected.
