The servers are back up as far as receiving results but not as far as distributing new workunits

The servers are back up as far as receiving results but not as
far as distributing new workunits. We are simultaneously clearing
out the old download directory and preparing to move both it and the
upload directory to the Snap Appliance, along with the DB.

Allowing result uploads will ultimately speed both the deletion
of old workunits and results and the granting of credit. Credit
for the backlog of results will start being granted once we move
to the Snap Appliance and turn on the hierarchical directory structure.
