Make rate limiting for Mastodon Registration API less agressive and enable it by default.

See merge request pleroma/pleroma!1154

As discussed on irc. Unlike Mastodon our web interface for registrations
is using the same APIs regular apps would be using, so 5 requests per 30
minutes per IP could hurt valid use-cases when Pleroma-FE switches to
it. Also enable the endpoint by default, it makes no sense to
have it disabled when
1. TwitterAPI endpoint is there and always enabled
2. Unlike Mastodon, there is no way to get an account without using the APIs (makes me wonder why the setting is even there)

Also in this commit: minor changelog improvements.
