1394	difftool -listrun returns multiple rows for stack-stack diffs	bills	bills	"difftool -listrun -diff_id 37719 returns 42 runs. This is because
it is a stack stack diff and each skycell included has a different
stack_id so the select distinct doesn't filter out the different
skycells.

This causes the postage stamp server to get the same stamp
multiple times. 

The postage stamp server can work around this by adding a -limit 1
to the difftool command line"	defect	new	low		ippTools		normal
