remove spacing for firefox inline-block elements

http://yuiblog.com/sandbox/yui/3.2.0pr1/build/cssgrids/grids.css

.yui3-g {
    letter-spacing: -0.31em; /* webkit: collapse white-space between units */
    *letter-spacing: normal; /* reset IE < 8 */
    word-spacing: -0.43em; /* IE < 8 && gecko: collapse white-space between units */
}

cleaner:

<ul><li>
    stuff...
</li><li>
    more stuff
</li><li>
    ok, enough stuff, already.
</li></ul>

CSS inline/block nuances
White Space Collapsing: the 'white-space-collapse' property - it hasn't been implemented by any vendor as of yet.
