AP_Logger: Added units to CurrTot message

Units are not associated with the CurrTot message. AP_BattMonitor.h indicates the total current consumed is reported in mAh. This change sets the units for CurrTot to Ampere seconds and applies a multiplier of 3.6 to convert the reported mAh value to Ampere seconds.
