Remove moot version property from bower.json

Per bower/spec@a325da3

Intended to be used in the future when Bower gets a real registry where you can publish actual packages, but for now just leave it out.

As far as I understand it will be used again in the future.
Is there a problem with just leaving it in there? If we really need to remove it, we would also have to change the gulpfile (see gulpfile.js#L15) because we automatically update the version in the bower.json.

Considering bower core development is basically dead, I would strongly recommend focusing on NPM, not on Bower.

That's why I don't care if there is a moot attribute in there.
