Changed the T-Balancer fields for the actual PWM (percent) value of the channels from 156+ to 137+, because on some (older?) hardware the fields 156+ seem not to be updated. Fields 137+ have one bit less resolution, but it's what the Navigator uses as well (and used only if in PWM mode).

Fixed a typo in the parameter form.

Fixed TBalancer reading on hardware that uses 88 (instead of 255) as frame identifier.
