Update the wiki for v4.6.0 - Add the 4.6.0 release and upgrade pages in Chinese and English, with the steps to move from a local preview back to a stable build and a table of what moved since 4.5. - Home, sidebar and footer point at 4.6.0 and the current guide paths. - The 4.5 preset pages apply to 4.6.0 with the new menu locations; the 4.5.2 pages are marked as history. - Fix links to guides that moved in 4.5.2.
