Latest software

So I commented out the line calling the routine displaying text on the SID because it was causing issues with the I-Bus communications. For example, turning on either blinker, occasionally the indicators on the dash would not blink, or blink twice fast, as they time themselves with the outside blinker. The timing with the SID text display was interrupting this, and god knows what else. Of course, this is only an indication issue, the outside blinkers still work perfectly.
