Correct date label on project information page

The label "Created at" would be appropriate for a timestamp such
as "09:30".

However the timestamp is actually being displayed as a date in
the format "Oct 15, 2013".  In this case "Created on" is better.
Remove "is" from labels
Capitalise "Awesome" in placeholder text
Add smtp settings override in smtp_settings sample file.
Skip rdoc to speed up Ruby compilation
corrected the url of the init-script
Use init.d/gitlab script from 6-0-stable branch

Seems like init.d/gitlab script from master branch is not working anymore. Change to a version from 6-0-stable works fine.

It says:
```
Starting the GitLab Unicorn web server...
/etc/init.d/gitlab: 132: /etc/init.d/gitlab: script/web: not found
Starting the GitLab Sidekiq event dispatcher...
/etc/init.d/gitlab: 141: /etc/init.d/gitlab: script/background_jobs: not found
GitLab is not running.
```
