Multilingual Support

[drHyperion451]

I've made some improvements to support multiple languages. The main js logic is created, but there is still some work to do:

To-Do:

• JavaScript Logic.
  • Read json and change document
  • Change stuff that is being controlled by js. (The YES text, the latest solution...)
  • Warn the user if the language is not avaliable. Code
• Language UI switch. Code
• Support for right to left writing languages (hebrew, arabic...)
• Support for other writing systems than latin alphabet.

How does it work?:

It will use a query variable on the url. For example:

https://drhyperion451.github.io/?lang=es-ES
Sets the website to Spanish es-ES using a json file lang/es-ES.json. The link doesn't work because it's not deployed.
By default it's in English en-ENand it's not necessary to add the ?lang=en-EN variable to the url.
/lang/en-EN.json it's an example for all the people who want to contribute to the project.

Made an example translation for es-ES using automatic translation. Hope @MrTorfick improves it a bit.
