[MetroAndroid]

Automatically removing the "http://" when adding archive.org links breaks Ruffle Flash emulated content on many archived pages. To ensure compatibility, it seems best to to include that part of the URL when submitting the link.

Examples:

• https://web.archive.org/web/20130510144433/www.bleach.sega.jp/
• https://web.archive.org/web/20130510144433/http://www.bleach.sega.jp/
