Bug 16653: Display number of checkouts when exporting 'Most-circulated items' as CSV

Bug 16653: Display number of checkouts when exporting 'Most-circulated items' as CSV

reports/cat_issues_top.pl does not export "Count of checkouts" column as CSV

To replicate:

1/ Make sure that test instance has circulation in a given date range
2/ Go to Home › Reports › Most-circulated items
3/ Select a date range
4/ Select 'To screen into the browser' radio button, click submit.
5/ Note that Columns 'Rank/Biblioitemnumbers', 'Global' and 'Count of checkouts' appear in screen output.
6/ Click the browser's back button
7/ Change output to 'To a file', click submit.

Without this patch:
the columns "100/", "Global" and "Total" are exported to the CSV file.
"100/" contains the rank, "Global" is still global, and the "Total" column is empty.

With this patch patch applied, the last column is filled and the "Total" line is removed

(This script is really dirty)
