small css tweak

Hi,

IE doesn't understand border-spacing:0px; a portable alternative is
border-collapse:collapse;
Small color tweak, this is close to my personal preference, not sure
everyone would like it.

Thanks Cedric! This is really appreciated.

This patch is cumulative with the previous (I mean the previous one is
included). I don't know how to separate the two??

The easiest way is to just regenerate the patch from TOT.
