Opac changes

Made changes to the BIBIMAGE and FRAMEURL wwwoptions to allow Content Cafe book cover info to open in a new window/tab.

• The BIBIMAGE option now generates a [Close] button so that the user can return to the bib record or the browse list.
• The change in FRAMEURL affects the log on screen for E-Reserves in that there is no apparent way to return to the catalog. The browser back button should work in most cases.

Included WorldCat linking for the WEBADDRESS wwwoption and repurposed the z39 search button to link to WorldCat. The button is labeled "Other Libraries." The button appears on the button navigation row on the bib record. The code is set to retrieve catalog information for Austin area libraries.
