Add Language Support for DeltaScript

DeltaScript is a different version of JavaScript that made by ZtaMDev, I know that it is not popular but it actually very simple and easy to use, and they add some more like maybe and spec. And the most important is they use .ds file extension. I usually use it for my personal project in Visual Studio Code Insiders, and I wish I can use it in GitHub someday, Thank you!

Example

interface Person {
  name::str;
  age::num;
  tags::arr<str>;
  meta::obj;
}

func processPerson(p::Person) {
  spec.log("Procesando:", p.name)
  return p.name
}

Additionally, the .tmLanguage.json, and I recommend to use #7ed956.

(Sorry my English is not my first language so if I have some bad grammar please accept it, thank you!)
