    First implementation of general cell deviation checking and alerts
    is pushed.<br>
    <br>
    <tt>    Vehicle BMS: cell deviations & alerts</tt><tt><br>
    </tt><tt>    </tt><tt><br>
    </tt><tt>    Renamed metrics:</tt><tt><br>
    </tt><tt>    - v.b.c.level.* → v.b.p.level.* (for consistency)</tt><tt><br>
    </tt><tt>    </tt><tt><br>
    </tt><tt>    New metrics:</tt><tt><br>
    </tt><tt>    - v.b.c.(voltage,temp).(dev.max,alert)</tt><tt><br>
    </tt><tt>    - v.b.p.(voltage,temp).(min,max,avg,stddev,stddev.max)</tt><tt><br>
    </tt><tt>    </tt><tt><br>
    </tt><tt>    New configs:</tt><tt><br>
    </tt><tt>    - vehicle [bms.dev.voltage.warn] -- threshold [V]</tt><tt><br>
    </tt><tt>    - vehicle [bms.dev.voltage.alert] -- threshold [V]</tt><tt><br>
    </tt><tt>    - vehicle [bms.dev.temp.warn] -- threshold [°C]</tt><tt><br>
    </tt><tt>    - vehicle [bms.dev.temp.alert] -- threshold [°C]</tt><tt><br>
    </tt><tt>    …all optional, default: warn at 120% stddev, alert at
      200% stddev</tt><tt><br>
    </tt><tt>    </tt><tt><br>
    </tt><tt>    New commands:</tt><tt><br>
    </tt><tt>    - bms alerts → show cells with warn/alert levels</tt><tt><br>
    </tt><br>
    <br>
    I changed the config scheme hoping a manual configuration normally
    isn't necessary with this automatic adaption to the standard
    deviation.<br>
    <br>
    Please check and report if that idea works. If it doesn't, please
    report the deviations and necessary threshold levels on your
    batteries.<br>
    <br>
    I also omitted the overall stddev alerts for now, I don't think
    those really are necessary, haven't had a single trigger on the
    Twizy for this.<br>
    <br>
    Integration into the web chart page and historical data updates are
    still todo.<br>
    <br>
    Migration for the Twizy battery monitor to the generalized scheme is
    in progress.<br>
    <br>

              Yes, you can add a new menu to PageMenu_t like that. I
              suggest introducing a general tools menu instead of a
              specific one, i.e. "PageMenu_Tools".<br>
              <br>
              To still fit the menu on one line in tablet mode (width
              down to 768 px) I suggest moving the Shell into the tools
              menu then.<br>

                                                          the Model S is
                                                          to keep a

                                                          For example,

                                                          we set the

                                                          The

                                                          be SOCKS, and

                                                          Another is
