KTCC as online Service + docker image

[soywiz]

I have converted KTCC to be a multiplatform Kotlin project.
And I have created a website that uses the compiler and provides an IDE to edit C code directly in the browser + converting code to Kotlin directly.

Also, since now I can compile to native too, I have provided a docker image with the CLI without requiring the JVM:
