Add back various pages from old site

[anjackson]

As well as #4 , we could consider adding the following pages to this static version.

• info/searchHelp (check integration with current search)
• info/privacy (forward to BL)
• info/nominate (part of UKWA-UI)
• info/contact (part of UKWA-UI)
• info/mementos (about the mementos service)
• info/links (links to other web archives etc.)
• info/copyright (forward to terms_conditions?)
• /statistics (Could add as an alias to a new info/statistics page, but perhaps should be API driven rather than CMS?)

This list is based on browser https://www.webarchive.org.uk/wayback/archive/20140219074906/http://www.webarchive.org.uk/ukwa/ etc.
