Remember redirected URLs as visited

"visited.txt" will now remember URLs that were redirects, but those are not shown in the UI as part of the history. This fixes the issue where redirected URLs were not being shown as visited links in the UI.

Beware if downgrading Lagrange: URLs in the history will get prefixed with "0000 ". Might be a good idea to switch to a forwards compatible format like JSON for these files.
