Grid builder generates CSS with word-spacing for pure-g-r

[Perturbatio]

The grid builder generates CSS with word-spacing for pure-g-r and the opera-only hack in the generated CSS, AFAIK it's been removed from the default grid elements now since it isn't needed and causes issues with chrome

In line with what Perturbatio is saying, there are a couple items that are being left out of the generated code from the code builder:

(uncompressed)
031 font-family: FreeSans, Arimo, "Droid Sans", Helvetica, Arial, sans-serif;

040 display: -webkit-flex;
041 -webkit-flex-flow: row wrap;

044 display: -ms-flexbox;
045 -ms-flex-flow: row wrap;

256 word-spacing: -0.43em; /-- asterisk is missing --*/

274 font-family: FreeSans, Arimo, "Droid Sans", Helvetica, Arial, sans-serif;

283 display: -webkit-flex;
284 -webkit-flex-flow: row wrap;

287 display: -ms-flexbox;
288 -ms-flex-flow: row wrap;

Also, none of the (what I believe to be) IE width percentage hacks are being included as well.

I'm not versed enough to know what can or cannot be excluded, I just know that when I include this into my custom generated code, it works.
