Bug 37775: Remove delayed commits from update_totalissues.pl and add progress option

This patch removes setting AutoCommit to 0 and commiting only every X records.
Instead we commit as we go and report progress using a parameter.

Bug 36474 reduced the numebr of changes that are being committed, so this should be a reasonable change. The
use of commits without transactions was causing problems if the library was active while the script ran.

To test:
1 - perl misc/cronjobs/update_totalissues.pl -c
2 - Script runs, but with unknown parameter
3 - perl misc/cronjobs/update_totalissues.pl -p 10
4 - Script runs and reports every 10 records
5 - per; misc/cronjobs/update_totalissues.pl
6 - Script runs and reports every 100 records by default
