Add: Open Graph / Meta Data

Would be cool to add Facebooks Open Graph.

Right now I'll use the custom code container, but in terms of making your software better, it would be cool :)

Nuts! I can't put the custom code container inside the <head>, so it won't work :(

Great suggestion! We have to add this. The Page Properties dialog is very limited right now. We will enhance it so you can add any meta tag that you need. We may also add presets for Open Graph and twitter cards in the next releases.
