restructured CSS3 to include default properties, and to have "named arguments"
Made the fields and buttons compatible sizes, switched padding to "px" instead of "em" for better compatibility.

Added some more specific height rules to the form fields for consistency.
W3C Validation, and navigation tweaks for IE7… IE7 is busted.
corrected the breakpoint mixin to have a smoother transition from monitor to tablet.
bottom margins on grid.
moving "intro" out of the masthead, so it can be used in other sections. adding pos:rel to the grid so we can position things absolute in the grid.
Updated media to no longer collapse for mobile. The majority of cases probably won't have 6 nested items like the example in the docs, and the fixes should be based on circumstance, not a default.
added btn-huge
Fixed up the grids. More accurate (and rounded) measurements, as well as some more options for aligning those grids: push, shift, stretch, etc.
More grid tweaks… the extras like push, shift and stretch are wonky when they become percentages (tablet), so there's a bit of work to do there still.
fixed the linear gradient thing to just accept a list of values.
whitespace fixes.
fixing some more white space.
fixing the stretch issues with the grids.
made a small change that let people setup the grids with or without unitless values, changed the name of the grid mixin.
fixed a small default height issue with the textarea.
max width if media-head is an image.
Making configuration options for the navigations.
removed -ms- prefix from linear gradient as it never existed.
fixing the css mixins to support multiple parameters without encapsulating them in strings.
