Add throttle limit settings to CMS

There have been a number of requests for this as it seems to be common for racers to tune these values and adjust the settings as they become more comfortable with a track. Previously the settings could only be adjusted in the CLI and required a computer. Adding them to the CMS makes it easy to adjust in the field.
