[Ovmsdev] Scripting - missing integrations

[Mark Webb-Johnson]

It seems we have OvmsNotify.Raise() already.

I am implementing OvmsEvents and OvmsConfig now.

I will just keep config simple (no access to protected variables) for the moment. We can revisit this if/when we have a secure way of setting App permissions.

Regards, Mark

I.e. the script needs to use a valid API token to access protected configs. An API token could include a set of specific grants & denies, so we can extend that as needed to also cover other potentially critical stuff like network & file access. Similar to App permissions on Android / iOS.
