Convert OL page to i18n page

index.md

Script to convert a normal /type/page to a /type/i18n_page. Assumes the current page is in English, and creates the .en page with the same body.

~80% tested. I used it recently but then made some changes. You should be able to copy and paste it into your terminal, or it'll probably also work as a bookmarklet:
