JavaScript language module

[Kr0nox]

Adds a language module for javascript.
It just extends TypeScript, since every typescript keyword is also a javascript keyword.

I moved the js specific tests from the ts language module to the js language module

@Kr0nox the language loader should check for language interface implementations, and thus the Javascript module should be mentioned when the dependency in the CLI module ist set...

The Language Loader currently uses the getName method of a Language. Currently this returns the Parser for every language. As you mentioned it should mention the javascript method, but the parser still is the typescript parser.
@tsaglam How do you want that handled?

I would say this is an internal detail that is not important for users. So it is fine when it says javascript for now...

[Kr0nox]

But it gets mentioned when starting the CLI in this message

LanguageLoader - Available languages: '[C/C++ Scanner [basic markup], C/C++ Parser, C# 6 Parser, EMF metamodel, EMF models (dynamically created token set), Go Parser, Javac based AST plugin, Kotlin Parser, LLVMIR Parser, Python3 Parser, R Parser, Rust Language Module, Scala parser, SchemeR4RS Parser [basic markup], SCXML (Statechart XML), Swift Parser, Text Parser (naive), Typescript Parser]

But i can still change it to JS if you want that

I think I may have misunderstood something, let's discuss it tomorrow, that is probably easier. :D

Just one minor issue.
