v0.9.8 bugfix update

Debug poll timer of 60 seconds got committed instead of 15 minute timer.

The per-submit-url good/bad send counts were not being zeroed between
urls, leading to odd log messages.

The submit loop drains the work_list to the first good url.  It then
should break rather than continuing to loop testing the connection to
possibly remaining submission urls in the url array, despite there being
no work to send them.

If none of the urls worked, the loop completes with work_list still
holding data, which becomes the requeue_list.

Thanks to William Douglas <william.douglas@intel.com> for the bug report!
