1.3.0

Added item to component to store a second location code.  When a physical and
a logical location code can both be constructed, we will store both but display
the physical code by default.  The logical code will be available using the 
-D/--debug option on any of the output programs.

Added logic to sysfscollector to query SCSI drives for their physical location
code.

Added logic to devicetreecollector to contruct the physical location code if
the information to do so is present.

Added a signal handler to vpdupdater that forces Berkeley DB to cleanup on
exit.  We were seeing vpdupdater hang the boot process because a previous
run had not exitted normally and Berkeley DB would wait forever to acquire a
lock on the DB.
