Minor release to add carousel indicators, improve tooltips, improve dev setup, and fix hella bugs.

• Repository changes:
  • Local instead of global dependencies for our makefile and install process. Now getting started is way easier—just run npm install.
  • Upgraded to jQuery 1.9. No changes were needed, but we did upgrade the included jQuery file to the latest release.
  • Moved changelog to be within the repo instead of as a wiki page.
• New and improved features:
  • Added carousel indicators! Add the HTML and it automagically works.
  • Added container option to tooltips. The default option is still insertAfter, but now you may specify where to insert tooltips (and by extension, popovers) with the optional container parameter.
  • Improved popovers now utilize max-width instead of width, have been widened from 240px to 280px, and will automatically hide the title if one has not been set via CSS :empty selector.
  • Improved tooltip alignment on edges with #6713.
  • Improved accessibility for links in all components. After merging #6441, link hover states now apply to the :focus state as well. This goes for basic <a> tags, as well as buttons, navs, dropdowns, and more.
  • Added print utility classes to show and hide content between screen and print via CSS.
  • Updated input groups to make them behave more like default form controls. Added display: inline-block;, increased margin-bottom, and added vertical-align: middle; to match <input> styles.
  • Added .horizontal-three-colors() gradient mixin (with example in the CSS tests file).
  • Added .text-left, .text-center, and .text-right utility classes for easy typographic alignment.
  • Added @ms-viewport so IE10 can use responsive CSS when in split-screen mode.
• Docs changes:
  • Added new justified navigation example.
  • Added sticky footer with fixed navbar example.
