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](https://github.com/twitter/bootstrap/pull/6713).

- **Improved accessibility for links in all components.** After merging [#6441](https://github.com/twitter/bootstrap/pull/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](https://f.cloud.github.com/assets/98681/25869/5e2f812c-4afa-11e2-9293-501cd689232d.png).

- Added sticky footer with fixed navbar example.
