Manifest fixes, mostly for translation needs

Hi Jim,

I loved your previous Manifest theme so when you updated it with a fresh new version, I was very glad to use it on my brand new blog (http://www.la-renouee-des-sens.fr).
As you can see, this a french blog, and your theme was not perfect for translation.
I forked it and propose to you now some fixes.

Do not hesitate to contact me if you need.

Cheers,

Laetitia
