Remove jQuery reference in example 7

[Pustur]

Do I need to bump the version for this small change? Just ask if that's the case.

Closes #39

Also I think you forgot to push the 1.3.7 tag for the commit 383eccc.
Eventually the 1.0.0 tag is missing as well.

I increase the version number for every change (following semver) but do not publish a release (and a tag) after every version bump. Didn't publish the 1.3.7 as it was a very small and irrelevant change. The 1.0.0 was published for sure but removed probably because it was unstable, I don't really remember.

As long as this is a change in the docs and not in the libary itself you don't need to change the version number but if you would have changed it is also okay for me.
