Bug 8017 reduce manipulation of GetAllIssues return

GetAllIssues can produce large lists
For performance purposes:
Dont loop over the list without cause
Dont do expensive processing in the loop
Dont needlessly copy the array
Do display formatting in the template
Dont extract the barcode list unless we are producing it
Reduce db calls by using the data to hand

Make the table in the template a bit more readable
where everything was stuffed into one line
