Autofix broken Confluence links

[nwiltsie]

This PR replaces links to the old Confluence wiki in all plain-text files in this repository. I manually created a table of replacement links and used a regex to find and replace them - it's very possible something was mangled in that process, so whoever reviews this should confirm each of the replacement links.
