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
Apply @color argument to striped gradient

The @color argument is currently not being used for the striped gradient.
Remove progress bar striped @color parameters; use default transparent white.

* If the @color parameter is not removed, the stripes are the same color as the element background color. In this case, the stripes do not appear.
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
code.less: also set default monospace font for `<kbd>` and `<samp>`
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.

Merge branch 'master' of github.com:twbs/bootstrap
Always wrap form examples in .bs-example; add some missing role='form'
Fixing carousel control positioning

The left control should be positioned from the left, while the right
control should be positioning from the right. Positioning both from the
left results in the right carousel control being incorrectly positioned
(most noticeable with a larger than normal font size).
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
