Twenty Twelve: line-height style fixes, props chellycat. See #21486.

 * For entry titles match larger screen style with the base styles to add a bit more line-height.
 * Add line-height to entry-content and entry-summary, so that elements appearing outside of paragraph tags inside these containers will still have the appropriate line-heights.
 * Add line-height for pingbacks, which looks a bit too tight when pingbacks span multiple lines.
