Typo in a link on the "What is Flux" page

[DaniloGimenez]

There is a typo in a link on the "What is Flux" page, in "Further Reading" section:
For a more in-depth look at the Flux architecture, check out Flux Application Architecture ....

There is a ".html" in the link, but it should be "/":
current link => http://facebook.github.io/flux/docs/overview.html
correct link => http://facebook.github.io/flux/docs/overview/

Thanks!
