Fully respect grid settings

[peburrows]

Make sure all the values required to setup the grid are dynamic and pulled from user-defined variables instead of being hard-coded.

is your whitespace off here? are you using tabs instead of spaces?

[peburrows]

No, I'm using spaces instead of tabs.

The whitespace changes (automatically done by the Save command in TextMate setup because of a whitespace bundle I have installed) are either a) removing trailing whitespace, or b) converting tabs to spaces.

Ah, interesting about the tabs/spaces. I'll run through our files once more and check for any spacing issues—we should be using soft-tabs with 2-spaces. Thinking about this now, we should add it to the docs for contributors.

@peburrows, can you run the make to get the compiled CSS as part of this pull?

[mdo]

Actually, making this part of the next release. Got it accounted for in the 1.2-wip branch we have right now.

Thanks!
