Breadcrumb Rich Snippets Microdata

Using Google rich snippets tools
(http://www.google.com/webmasters/tools/richsnippets) and I found out
that the microdata format is not completely correct.

I think the changes I made fixed that issue.

Please remove the unnecessary concatenations around the `itemprop` span.
