change navigation and permalink base url

[Andrew Newton]

I installed Roller using Tomcat's built-in HTTP connector on port  
8080.  After I got everything up and running, I switched over to using  
an AJP connector through Apache HTTPd on a virtual host dedicated to  
the Roller blog (so both the domain name and the port number are  
different).

Though I can access the blog just fine through HTTPd, Roller still  
uses the old port 8080 URL for permalinks and links it puts in the  
navigation menu.  How do I get Roller to quit using the old port 8080  
URL?  Any help would be appreciated.

I'm running Roller 4.0 on Centos 5 with Tomcat 6.0.16 and Java  
1.6.0_06-b02.
