Add versioning to sandbubble

[guihkx]

Hello!

How do you feel about versioning sandbubble?

Right now, sandbubble itself isn't versioned (git or otherwise), and nor are its config files.

I think making sandbubble versioned would make it easier for distros packagers to distribute it, naturally increasing user adoption (assuming that's something you want).

Another semi-related suggestion is the versioning of config files: If in the future you wish to change the layout of the file, having some sort of 'version' key in the file may help you retain compatibility with the old format.

Anyway, let me know what you think.

Thanks!

Those are both good ideas.
