/**
 * Base button styles – Based on csswizardry.com/beautons
 *
 * 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. Fixes odd inner spacing in IE7.
 * 9. Don’t allow buttons to have underlines; it kinda ruins the illusion.
 *10. Prevents from inheriting default anchor styles.
