Should re-organize directory structure for multiple languages

[petehouston]

Let say others want to add different languages, so the directory js in one pic.mindnode should be updated to reflect the change. I suggest like this:

[LANG]
|    |---project-js-in-one-pic.mindnode
|    |---project-js-in-one-pic.pdf
|    |---project-js-in-one-pic.png
|    |---project-js-in-one-pic.svg
|
|---README-[LANG].md
|---README.md

This way, all other forked projects can be easily synced and fit into the upstream project.
