Better title and social sharing

If I share http://madewith.meteor.com/apps/trenzi.meteor.com on Facebook I get: the Homepage description as title and not the content title.
Maybe this bad beavior can be fixed integrating https://github.com/DerMambo/ms-seo

Start by reproducing the Facebook share preview for the Trenzi page and inspect how its title and social metadata are generated. Review the suggested ms-seo integration, then verify that sharing a page uses its content title rather than the homepage description.
