Partial rewrite of ore rebalancing code. It's now simpler and doesn't
make any
special cases for furnaces - removed a lot of furnace-related code.
Added power crisis mode, where refineries and assemblers are shut down
to
conserve power.
Renamed "throw out stone" to "throw out gravel", and made it so that
only
gravel is thrown out.
Updated ore ratios to new values, including accounting for the fact that
stone
can now produce multiple ores.
