[Ovmsdev] Vehicle Support Checklist

I've updated the development document with some vehicle module development checklists. You can use these checklists to know what vehicle parameters the OVMS system supports, and how you can map a specific vehicle to these.

The Tesla Roadster supports 100% of these (obviously). It would be good to use these ongoing for other vehicles, both as a target list to get to 100% support, and as a worksheet for both CAN bus information and progress.

I hope you find them useful.

Regards, Mark.
