Fix active tab padding-bottom to remain untouched, reverting a line added in r11335.

The line actually reduced the padding-bottom from 0.3em to 0.2em, which broke
the active tab effect for webkit browsers (including Safari and Chrome), but
not in Firefox. Appearance of active tab is now again the same as non-active
tabs with mouseover.
