[Ovmsdev] Introduction - message replay and other topics

[Ludovic LANGE]

Michael,

You're absolutely right, I did not have a look at the web UI (Config / 
Wifi) while researching this feature, and have been only using the shell 
for the configuration and the doc.

In order to complement the existing doc, please find here an update 
proposal: 
https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/pull/746

Regards,

Ludovic
