Updating snippets for Atom

[jeanmachuca]

Please I need to update the snippets for Atom. Your code contributions are very welcome!
Learn more about Atom here:

https://atom.io

And learn more about QCObjects Atom extension here:

https://atom.io/packages/qcobjects-syntax

It is needed a way to synchronise the versioning of both packages, as well as updating the snippets to the last version of QCObjects.

If you got any proposal about how to enrich the extension for Atom you are very welcome as well!

Thanks
