quick fix for docs mention
Add role="toolbar" to elements with .btn-toolbar.
add variables for heading font sizes; fixes #9921
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
deprecate @screen-{phone,tablet,desktop} vars
Merge branch 'master' of github.com:twbs/bootstrap
add David (david-dm.org) badge to monitor currentness of dependencies
Always wrap form examples in .bs-example; add some missing role='form'
Added glyphicon-block class

Prevents elements moving around the page after the font file has loaded by setting a defined width on elements using the icon font.
Removed glyphicon-block instead target :empty .glyphicons
