Direct users to gelbooru when they try to connect to booruview

Booruview dev here

The site gets a handful of LS users each day trying to connect, but it fails (booruview is just an alt frontend to gelbooru). The actual requests themselves aren't an issue, but maybe consider adding some UX to point the user to gelbooru.

Thanks for the heads up. I'll probably add an auto replacement of booruview.com to gelbooru url without any extra warnings to avoid adding extra localization
