- Metrics: extended reboot persistence: most vehicle state and long term 
     metrics will now retain their values over a reboot (e.g. OTA update)
- Metrics: new standard metrics for grid integration (V2G) / generator role
   New standard metrics:
     v.c.kwh.grid            Energy drawn from grid during running session
     v.c.kwh.grid.total      Energy drawn from grid total (life time)
     v.g.generating          True = currently delivering power

- TPMS: metrics rework & standard alert notifications on new v.t.alert 
   Replaced metrics…
     v.tp.fl.p               TPMS front left pressure
     v.tp.fl.t               TPMS front left temperature
     v.tp.fr.p               TPMS front right pressure
     v.tp.fr.t               TPMS front right temperature
     v.tp.rl.p               TPMS rear left pressure
     v.tp.rl.t               TPMS rear left temperature
     v.tp.rr.p               TPMS rear right pressure
     v.tp.rr.t               TPMS rear right temperature

1=warning, 2=alert]
     v.t.health              TPMS tyre health states
- New standard metrics for total (life time) energy and coulomb

- Events: added automatic events on v.e.aux12v changes.
   New events:

- Location: add metric for name of current location
   New metrics:
     v.p.location        -- Name of current location if defined

- Server V3 improvements:
     a) On first connection to MQTT broker we used to send all metrics. Now
        we only send metrics for which we have a value.
     b) New config settings:
          "updatetime.on" which sets updatetime when the car is on (driving)
          "updatetime.charging" which sets updatetime when the car is 
          "updatetime.awake" which sets updatetime when the car is awake
        If unset the server uses the "idle" or "connected" interval as 
     c) New config setting "updatetime.sendall". If you set this we will 
        _all_ valid metrics at this interval. Helpful to keep a steady 
flow of
        values for charting.
     PLEASE NOTE: These settings will increase OVMS' data usage.

- Wifi: option to immediately disconnect/reconnect on bad signal level
   New config:
     [network] wifi.bad.reconnect [bool], default no
- WiFi: replace fixed scan times by config instances
   New configs:
     [network] wifi.scan.tmin              Min scan time per channel 
[ms], default 120 ms
     [network] wifi.scan.tmax              Max scan time per channel 
[ms], default 120 ms

- Updated wolfssh and wolfssl so the restriction of clients to use
   aes128-cbc cipher is no longer required.
