1.6.4: Fixing TE3 compatibility, power taps

Power taps were not emitting power. Fixed & optimized.
RF production was wicked low. Boosted to nicer levels, an
4-column-2-height reactor will now produce 80-100 RF/t. This may go
higher in the future.
Machines have had their power buffers increased to compensate for the
move to RF and its higher values.
Cyanite reprocessing is now considerably more expensive: 2000 RF per 2
ingots.
