safely wrap title: contents using json dumps

This should handle any arbitrary punctuation marks which may happen to
be in the Title - `",',\,*,...etc`.

I don't undersand why this works, since we're not doing anything with 
json. I just know that everything I've thrown at it comes out safely.

I left the change from pelican-plugins#15 intact, though json.dumps makes it 
unnecessary.
