Subject: [PATCH] Twenty Twelve: move Open Sans custom font loading to a body
 class to allow easier overriding, fixes #21694.

 * Use wp_style_is() to check for the enqueued CSS file before adding the body class value.
 * Add a sample dequeue method in the comments as documentation for child themers and their ilk.

Props viniciusmassuchetto, nacin, and obenland.
