Well, now that we have this new `:views_prefix` option, why would we enforce a `kaminari` directory? It's more flexible this way, and as this is a non-standard option people who use it will know what they're doing.

Initially, I left the `kaminari` hard-coded in the path, but then realized it's just a default. Trust me, if we leave it there hard-coded the next issue will be _":views_prefix is great, but how can I rename kaminari.....?"_ :)
