[Ovmsdev] ACC implementation

Re-reading this, I think I may not have been clear. What I mean, at a high-level, is:
Have a facility to create and maintain ACC charging profiles. Make them optionally connectable to locations (so they auto-activate in that location), but also just generally available for manual activation.
Ignore homelink, it is irrelevant to ACC.
Implement the ACC implementation itself in the base vehicle module, in a way that vehicles can implement/override this core charging functionality, but that we can bring the power of ACC to all vehicle types. For example, if a vehicle doesn’t support timer charging, we can do it.
I hope that is clearer.

For example, have functions to set the charge type (on-plugin, at a specific time, complete by time, etc) and have a base implementation that does it from ovms if the vehicle implementation can’t. So long as the base vehicle implementation can do ChargeStart and ChargeStop, the rest can be built on top.
