Prepare for merging in master to this branch.
Prepare for merging in master to this branch.

Serial numbers were altered in master in commit 292f4a8.  Since I moved
serial creation to another file on this branch (utilities.js), merging
master into this branch would not update this method.  I think there's
probably a more gitly way to make this change, but I don't know what it
is.

Later, when I merge the admin changes (see branch 128-status-field) with
this branch there will be more problems.  I'll have to update the
methods in utilities.js with the changes from the admin updates.
