Subject: [PATCH] Players now lose power over time while they are offline. New
 conf.json setting "powerOfflineLossPerDay" (default 1.0) is how much power
 they lose; note that this power loss actually occurs frequently in very tiny
 amounts as time passes, not just once per day. New conf.json setting
 "powerOfflineLossLimit" (default 0.0) which will stop offline power loss once
 a player's power drops to the specified amount. As an example, the default
 1.0 power loss per day offline is roughly 0.0417 power loss per hour, 0.00695
 per minute, and so forth.
