Refactor file layout
scrub twiki usernames The twiki username links are no longer used since converting to ikiwiki, and contribute to the large number of dead links. Convert these from camel cased wikilinks to regular text.
reorg: remove the AFSLore subdirectory The AFSLore subdirectory was left over from the previous wiki. Move everything here up to the top level. A redirect rule will be added to the apache config in case anyone has links to the old paths. Change-Id: I39c17cf7363d8c90987859d34a2873ffc9e90ed0
