Bug 27513: Add notes to variables for report parameters template

This patch adds the TT variable 'notes' to the variables
that guided_reports.pl passes to the template guided_reports_start.tt
during SQL parameters entry in the phase 'Run this report'.

To test:
1. apply the patch
2. navigate to Reports -> Guided Reports -> Create from SQL
3. create an SQL report that includes at least one parameter, e.g.:
   SELECT barcode FROM items WHERE homebranch=<<Select library|branches>>
   the actual SQL and name of the report doesn't matter much, just make
   sure that you also put a note e.g. "Test text for display" in the
   field "Notes:" before you save the report.
4. run the report
5. the note you entered should now be displayed below the heading
   "Enter parameters for report..."
