Layout options alignwide or alignfull are missing

[Sal Ferrarello]

This is a great resource - thank you.

The full-wide example is a little confusing as the layout options do not include alignfull even though it is being used.

I suspect if we add

add_theme_support( 'align-wide' );

to functions.php, we can add both the alignwide and alignfull layout options.
