Grid renders slightly differently on Safari

[cvrebert]

Example: http://jsfiddle.net/wyrefkmg/4/

OS X Chrome (which is nearly identical to OS X Firefox):

Safari v7.0.5 on OS X 10.9.4:

Note how the 6 and the 7 aren't aligned, and how there's extra blue padding on the right edge of the first row.

Yeah... Safari's rounding errors are a nightmare and is a browser bug rather than a framework one as it would affect any percentile based grid system

There's not really a huge amount that can be done at present; the grid calculations are correct. Adding push or push-{grid range} to the last column would even things out a little but it's a bit hacky for my liking.

I should document it though to make sure people are aware of the issue. Fingers crossed Apple will do a better job with upcoming releases.
