changelog typo fixes

Add section for "Additional Configuration"

I had to dig in the source in order to figure out how to change the email_from on the CI server. I thought that this would be useful documentation for others afraid of source diving.

update to latest nginx ssl_ciphers

From https://gitlab.com/gitlab-org/gitlab-ce/blob/master/lib/support/nginx/gitlab-ssl

See merge request !243

Update nginx config to match GitLab repo

* Add `fail_timeout=0;` as added in https://github.com/gitlabhq/gitlabhq/commit/25ee53c3aea763f794948947a6f4c4fd422bbf7b & recommended by
http://unicorn.bogomips.org/Unicorn/Configurator.html#method-i-timeout when Unicorn is running behind nginx.
* Better match formatting to https://gitlab.com/gitlab-org/gitlab-ce/blob/master/lib/support/nginx/gitlab-ssl & https://gitlab.com/gitlab-org/gitlab-ce/blob/master/lib/support/nginx/gitlab

Helps with #328 (why does https://gitlab.com/gitlab-org/omnibus-gitlab/issues/328 not just resolve to show #328?)
