Fix navbar toggles

Rename component.json to bower.json

Fix layout for examples in getting-started

Fix for carousel indicators

- Removed mixins for generating grid classes
- Thus, we manually declare every grid class, from 1-11 (12th unit is
excluded as that's the same as no grid columns)
- No more need for `.col` base class (yay!)
- Negative indent the rows at tablets and above once again (ugh, still
working through this part)
- Add support for `.col-md` for tablet-specific grid columns
- Still need to figure out offsets, pushes, and pulls on other
devices—right now only available on desktop

using screen-size variables for grids

That's the new name of the Bower metafile.

Remove form-actions-bg

If form-actions has been removed, this variable is no needed anymore.

* Add start and end support to the horizontal gradient as well
* Change all variables from camelCase to use-dashes
* Better comments in the gradients mixins area
* Update current uses of gradients in dropdowns and carousel to specify only two values by direct assignment of variables

add show/shown hide/hidden events to dropdown + update dropdown links for testing + catch a few missed namespace things

Use base padding for input-group-addon class
