Accursed power loss!

1% for the short jumper cables, 5% for the long heavy-duty cables. No
loss on the non-spawning debug Shiny Cable.

Also, the BFS traversal is now encapsulated in a simple local method,
with a couple of lambda visitors in the charge_ and discharge_battery
methods to do the right job.

Also-also, left in some debug messages for making sure the values are
actually being calculated as expected.
Change volume and weight of cables.

The jumper cables should be lighter and less bulky. The debug cable can
be whatever it likes, but it might as well be impossibly light and
small. Makes for a better description, too.
Get off-map vehicles from the MAPBUFFER directly.

Also forces off-map vehicles connected to on-map ones to load by
traversing the graph of vehicles every turn (might be a bit excessive,
maybe? Doesn't seem to slow things down appreciably in normal gameplay).

Also lets off-map vehicles generate power and consume fuel if they're
still on a submap that's loaded; most of the time, this will be just the
few vehicles actually connected to an active power grid, but it might
include some others. It's at least as confusing as vehicles that don't
consume fuel outside the reality bubble, even though their engines are
on.
Make fuel_left also recurse for remote battery.

Only when figuring out whether to turn on consumers, though. Defaults to
off.
Slow-leak from the map instead of the vehicle idle

Now that vehicles can idle while they're off-map, we can't really
perform slow_leak in there. Moved it to map::vehmove, which had gotten a
little whiny about having barely anything to do.
