Bug 28653: Add new method RefreshIssuesTable

On patrons check out or details page, after renewing
loans they don't sort correctly when clicking on "Date due"
tab. Page has to be reloaded so that sorting works.
This patch adds new method RefreshIssuesTable to
checkouts.js. When loans are renewed or checked in, issues
table is reloaded to and due dates are sorted correctly.

To test:
1. Add 3 loans for patron.
2. Change due dates so you they are e.g. 07/01, 07/02, 07/04
3. Make sure you have renewal period set e.g. 5 days and
check your RenewalPeriodBase syspref (I use current date there)
4. Renew loan with date due on 07/01, it should now be 07/07
5. Sort loans by date due
=> Note that order from top to bottom is 07/04->07/02->07/07
or 07/07->07/02->07/04, not 07/02->07/04->07/07 as one would
assume.
6. Apply patch and repeat.
=> Note that issues table is reloaded ("Loading..." pop-up is displayed)
and that due dates are in correct order.
