Bug 28555: Improve logging for overdue_notices.pl

Bug 28555: Improve logging for overdue_notices.pl

Currenlty the output with -v from overdue_notices is a bit overwhelming and hard to parse

I do a few things here:
1 - Only show SQL if verbose > 1
2 - Add some separators to make it more readab;e
3 - Remove some redundant messages with branchcode and borrowernumber

To test:
1: perl misc/cronjobs/overdue_notices.pl -v
2: Notice you get a LOT of information all smushed together
3: Apply patch
4: perl misc/cronjobs/overdue_notices.pl -v
5: Less info, and easier to read
6: perl misc/cronjobs/overdue_notices.pl -v -v
7: All the info, but nicer to read
