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.
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
remove .btn-group

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

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
Add missing methods (rotateX/Y, perspective(-origin) and transform-origin)

Added missing mixins:
rotateX
rotateY
perspective
perspective-origin
transform-origin
Add mixin for transition-property

It's quite handy if a transition needs the same duration, timing-function or delay and only specific properties to animate.

Add role="button" to <a> buttons

These should really be <button> elements, but until that gets squared away, this will suffice.
Add even more  role="button" attributes

Missed the <a class="btw" in my regex search
