introduce ENVSYS_BATTERY_CHARGE, which is the same than an Indicator and it's used to know if the battery is currently charging or discharging. - Require two sensors at least for SME_CLASS_BATTERY to make the low-power condition work: a ENVSYS_BATTERY_CAPACITY plus ENVSYS_BATTERY_CHARGE. - Simplify sme_event_check_lowpower() and make it check the required sensors in the SME_CLASS_ACADAPTER and SME_CLASS_BATTERY classes. If the acadapter is not ready, trust the state returned by the battery device. Based on suggestion from joerg@.
