remove it.

As a new, novice user, I ran into an issue where my postgresql
password contained special characters.  After a brief conversation
with DenSchub on #diaspora, it was noted that while the example
database configuration had quotes added for mysql, but not for
postgresql, and it was suggested this be improved.

Previously we had only a Rails validation which ensured poll participation
uniqueness but this adds uniqueness control to the database level, so that
uniqueness is guaranteed even when changing data with avoiding Rails
validations.

Some podmins were confuse how they can disable this redirect and I think
the rule with two users can actually be a little confusing. I think the
main goal of this page to give the podmin a little start and I think
after they configured everything, the pod works and they found the link
to the wiki to make themself an admin, it is OK to remove the redirect.

Also it's bad for single-user pods where this page always stays active,
even if they are an admin, but have only one user. It's more useful for
single-user pods to have the login on the home page.

If a user scrolls just below the 1000px threshold and clicks the back-to-top button within 250ms, we'll never hide the button as the scroll event gets throttled away. That's rather inconvenient.

Camo only proxies images hosted somewhere else, so it doesn't make sense
to add the proxied versions to search engines. It only creates traffic
for camo when /camo/* urls are in search results.

When there were posts with many followed tags they were returned
multiple times, resulting in less than 15 unique posts. That resulted in
some posts to be missed in the stream.

Fixes #4503

We only return `nil` when we know the person, but don't know the key or
the key is invalid, so it doesn't make sense to retry in this case. When
the person isn't known and can't be fetched we raise a DiscoveryError
which will be retried.

Also the errors were moved to the `Signable` module in the last release.
