Title: vertical-rhytm and typography fix for small element

Hi!
fix for vertical-rhytm issue with `small` element.
`small` without forced line-height or vertical-align makes block-level element a little bit bigger then it must be with its line-height :(

checked in latest chrome, firefox. also bootstrap got the same fix for small in headings.
