Change of location on ECCO of QWI files

For a while now, QWI files on ECCO have been available at

/data/clean/qwipu/state

Updates to QWI R2013Q3 and R2013Q4: NH added back

For an arcane reason, our mirror script skipped New Hampshire QWI files (sorry to anybody in or from the Granite State). This is now fixed for R2013Q3 and R2013Q4. Prior releases were not affected, future releases should no longer display that bug.
