Improve the detection of unused tanks.

Browse Source 
The begin/end pressure for unused tanks is normally zero. But I noticed
that in some cases both pressure values are stored as 0xFFFF. Since that
corresponds to a pressure of 511.99 bar, this is most likely some
special magic value, and not a valid pressure.

Tanks where either the begin or end pressure is 0xFFFF are now ignored
too.
