 A question in IRC reminded me that there's no efficient way to check if a
 specific post format exists.  At the moment, `current_theme_supports()` is
 an all-or-nothing Boolean value ... either the theme supports post formats
 or it doesn't.  There's no way to check for specific support for a
 particular format, say, "aside."

 This could be added to `current_theme_supports()` pretty easily and is
 done so in the attached patch.

 - `current_theme_supports( 'post-formats' )` will return `true` if ''any''
 post format is supported
 - `current_theme_supports( 'post-formats', 'aside' )` will return `true`
 if the "aside" post format is supported
