Bug 9105: Second housekeeping followup

Bug 9105: Second housekeeping followup

Removing some unused variables.
Restoring timeout parameter that was only used in cataloging.
Restoring copyrightdate and editionstatement in row data for template.
Small adjustment at the end of the while loop with template vars.

Discovered while doing so, that the paging feature needs some further corrections; will propose a patch under a separate report.
