Move bgcolor over to the new infrastructure.

Browse source 
Note that I call is_htmltabledatacellelement in
synthesize_presentational_hints_for_legacy_attributes, rather than
is_htmltablecellelement (which was used in
get_simple_color_attribute_for_layout), because that function was never called
for th elements.
