A feed-in meter without an energy counter now gets a lifetime total

A feed-in meter that reports power but keeps no energy counter now gets its lifetime feed-in energy added up from the plant's inverters. Plants receive this with their next agent update.

• An inverter that goes quiet credits its whole missed production with its first reading back.
• The lifetime total never falls back, and adding or replacing an inverter leaves it where it is.
• A jump larger than the plant could physically produce is not counted towards the total.
• Where a physical meter reports the value, that reading is used instead.
