Typography Refresh - Apply line-height to correct ID

The 1.6 line-height (@content-line-height set in variables.less) in
the Typography Refresh has been applied to div#content, which is in
turn overridden by the 1.5em line-height of #bodyContent
(set in common.less).

Fix: Remove line-height rule for div#content and set
line-height for #bodyContent to @content-line-height.
