Fix small typo in README.md

[jasonm]

This pull fixes a small typo in the README.md, and also will serve as an example for the Molajo/Filesystem CLA at http://www.clahub.com/agreements/Molajo/Filesystem.

Hmm, only TravisCI seems to be updating the status here, I'm looking into why CLAHub isn't also updating the status.

@jasonm - you absolutely rock. You are providing a much needed, missing service.

I walked through the steps. That was helpful, so very easy to do, nice to download the data and have those signatures. Thanks very much.

Maybe I did something on the webhook? Let me take a look on my end.

A-ha! It looks like CLAHub did what it was supposed to that time:

Thanks for the kind words @AmyStephen. So I think I have a good idea of why CLAHub was on the fritz that time.

It'll still be a little wonky until I work out clahub/clahub#27, with TravisCI and CLAHub both setting commit statuses, but you can at least look at the list of signees on clahub.com in the meantime.

Goodness, @jasonm - wow - that is really nice! That prevents any commits from occurring absent an agreement.

Cool. I'll keep an eye on #27. You let me know if having access will help.

Cheers!

BTW - the message is also in the status area for the issue report. So, it is very clear.

AND - it's right on the merge bar -- with a Merge with Caution note -- and the message right above.
