    $BASE
\*------------------------------------*/
/**
 * Base button styles.
 *
 *  1. Allow us to better style box model properties.
 *  2. Line different sized buttons up a little nicer.
 *  3. Stop buttons wrapping and looking broken.
 *  4. Make buttons inherit font styles.
 *  5. Force all elements using beautons to appear clickable.
 *  6. Normalise box model styles.
 *  7. If the button’s text is 1em, and the button is (3 * font-size) tall, then
 *     there is 1em of space above and below that text. We therefore apply 1em
 *     of space to the left and right, as padding, to keep consistent spacing.
 *  8. Basic cosmetics for default buttons. Change or override at will.
 *  9. Fixes odd inner spacing in IE7.
 * 10. Don’t allow buttons to have underlines; it kinda ruins the illusion.
 * 11. Prevents from inheriting default anchor styles.
