Drop hostname from cache key

By default, Rails will cache

    example.com/mywiki/show/SomePage
and
    www.example.com/mywiki/show/SomePage

In Instiki, this just leads to stale cached pages and frustration.
Fix that behaviour.

# to remove hostname in fragment caching
# so instead of caching different fragments for "example.com/posts/list" and
# "www.example.com/posts/list", instead it will just use "posts/list"
