Bug 11491: add option to supply field names in reports web service output

Bug 11491: add option to supply field names in reports web service output

The staff and public catalog reports web services (/svc/report) return
JSON output, in particular an array contain an array for each row
of the report output.

This patch adds a URL parameter, annotated, which when supplied and
set to a value that evaluates to Perl true, will cause the output
to be emited as a JSON array of hashes, where each hash represents
a row of report output and the hash keys are the column names
or labels set in the report definition.

This patch also moves code around to make diffs between svc/report and
opac/svc/report smaller.

The suggestion to return an array of hashes was made by Chris Cormack.

TEST PLAN
---------
 1) Log into staff client
 2) Reports
 3) Used save reports
 4) Click the Action button on any report
     WITHOUT PARAMETERS.
    -- with parameters blows up in master and this.
 5) Click Edit
 6) Make the report public
 7) Update the SQL
 8) Note the ID number of the report
 9) Note the ID number of a non-public report
10) Make up a crazy ID number for a non-existant report
11) In a new tab (with the appropriate edits)
