regenerate customizer's raw-files.js
add header font size vars to customizer page
rename @screen-XX to @screen-XX-min for clarity+unambiguity
Added fonts to "main" files

When using bower the "main" property is used to specify the files that should be consumed by applications including the package as a dependency.
Without including the fonts in this array the glyphicons do not work correctly as the relative font paths do not work after the "main" files are copied into my projects public dir using tools like https://github.com/yatskevich/grunt-bower-task

For now I have manually copied the fonts dir in the location needed for my project. But by accepting this pull request this will not be necessary for me or for other people that use bower.
fix #9941
removed reference to button color and gradient

Changed the wording to reflect the default button's new look since it's no longer grey and doesn't have a gradient. I'd say this new wording isn't ideal and needs something a bit more, well, descriptive.
removed extraneous space
deprecate @screen-{phone,tablet,desktop} vars
remove .btn-group

The example doesn't use .btn-group and adding the class causes "bad things to happen," as the saying goes.
