Site urls need to be specified outside of site

[ghost]

Currently, every site contains all urls that it can be reached under in the site.xml:

`

http://test:8080 http://localhost:8080 http://127.0.0.1:8080 http://127.0.0.1:8080 http://localhost:8080 http://test:8080 http://test http://127.0.0.1:8080 http://test:8080

`

While this is working to a certain extent, it would be helpful to be able to specify these urls later on. Not sure though if that is possible, since the site urls are used to create urls to files on the server during preprocessing etc.
