Bug 5379 - import_borrowers.pl fails with db insert/update errors

Some spreadsheet programs use smart quotes which causes the db to throw
an error when an insert/update is attempted due to improper processing
of the CSV file. This patch adds code to check for smart quotes and change
them to "dumb" quotes.

This patch also adds more logging of errors and a notice to the user to check
the logs for errors when they occur.
