Start for the localize subdomain, where it will be possible to translate MovLib:
* Created nginx configuration
* Created StartSSL certificates
* Changed the behaviour of the language selection page and what is done if no locale is set while creating new I18nModel instance. This is important because language independent subdomains like the localize one do not have a language code. Instead the language code is dynamic (either from the user's account, from the HTTP accept language header or our default language).
Overhauled to comply with latest changes to route generation process and make usage of server variables sent by nginx instead of hard coded strings.
