Gold partners: remove i18n

These offers change occasionally, are only available in the US, other
parts of these pages aren't i18n, and phrases like "10% off" cause
issues with Babel, so it's just a lot simpler overall to drop this.
Gold partners: Add Rover.com and SOL Republic
Mod log: add support for sticky/unsticky
middleware: Add a request.fullurl.
redirect: Use fullurl instead of url.
