Three things need to happen in the Welcome screen:
1. Search for any references to netbeans.org and remove them or replace them with references to Apache NetBeans, probably to https://blogs.apache.org/netbeans.
2. Remove the 'News' column, which is received from the NetBeans.org backend at Oracle.
3. Change the title of the Blogs column to News, i.e., there will only be one column, and the content of that column will come from https://blogs.apache.org/netbeans.
