Support Meta Tags (OpenGraph / Twitter Cards)

[tomdale]

Right now there's no way for an Ember application to put content into the <meta> tag of a page. This is necessary for FastBoot, especially for OpenGraph and Twitter cards. This will likely require an extension to Ember itself, although maybe we can do something as a quick workaround until a full solution is in place.

@tomdale - It is possible and currently done by at least one addon 😄. #66 (which supercedes #49) adds support here and ember-fastboot/fastboot#1 adds support to ember-fastboot-server.

@rwjblue Ah nice, thank you!

@ronco is working on this in #66 but is blocked

#114 + server #15 and ember-cli-head will meet this need until Ember provides full document population.
