Other fixes thrown in for good measure:
- Adding data to the results table to match output of returns
- Better checking of error codes in the script to control
output of error messages (don't show error box when there
are no errors).
- Move some errors/messages from the right column onto the
top of the page to match Koha's established pattern.
