MEB: Improve MEB status output. (#983)

Browse source 
* Add 4 missing status outputs from battery to MEB more battery page.
BMS_fault_performance
BMS_fault_emergency_shutdown_crash
BMS_error_shutdown_request
BMS_error_shutdown
* Adds SOH calculation.
* Fixes: (hopefully) the capacity calculation from Ah to kWh.
* Only update capacity and soh if number of cells is set. Remove incorrect scaling on Wh_max.
