ACT can handle damagable items correctly now

Note it still can't (and probably won't ever be able to) handle
wildcarded subtypes like different colored wool.
Reduce Oil chance in deserts, etc...

Blame this one on myst's flatlands.
Changes for 3.7.0 build.
Removed a bit of unneeded code in the Wood PPipe

@King_Lemming this will break compat with RS Cells because you're doing
it wrong. Don't use powerRequest() like that and don't ignore the return
of receiveEnergy().

PS. It was already broken because the cell was just throwing power away
because it was ignoring the return of receiveEnergy().
Cleaned up engine power display
Fixed a bug that was causing pipes to leak excess

This is an interesting commit, it not only fixes the RS Cells
(@King_Lemming) it also makes it so the network can respond to demand as
needed by shutting down overheating engines, since the pipes won't
accept power now unless something is requesting it.
