Added $rem-base to be default 16px font size. Used to calculate rem-calc

Switched emWidthCalc to use Foundation’s rem-calc.

Set up $small-range, $medium-range, and $large-range, if needed we can
expand out with the xlarge and xxlarge
Only set our ranges in the global _vars.scss

The media queries $small-up, $medium-up, etc.. are defined within the
foundations global.

Also $rem-base is already set to be 16px within the foundations globals.

I reordered the imports once more on the generator this should allow us
to override completely.
Merge branch 'master' into addon/global-foundation-vars
Switched the WSUHeader v5 to use the '@media #{$medium-only}' style media queries.
Fixed some minor issues with the wsuheader fd5.
Updated the print style for the wsuheader fd5.
Removed the unneeded _functions and _mixins.
Fixed the wsuglobal.scss so it is actually useful.
Added a package.json file.
Merge pull request #2 from waynestate/addon/global-foundation-vars

Foundation Media Queries added to global _vars.scss and cleaded up any legacy duplicate mixins.
