Match .carousel-inner specificity to beat styles

'.carousel ing' was replaced with '.carousel-inner > .item > img' in
3.0 and now loses the specificity war. To make carousel images 500px
tall, match specificity to make carousel.css win.
Update carousel example JS path

'bootstrap.min.js' lives in '../bootstrap/js' now. Switch to the
minified version for a smaller download since this example is focused
on CSS changes, not JavaScript ones.
Replace 'input-block-level' with 'form-control'

'input-block-level' was replaced with 'form-control' in v3. To get
block-level inputs, the 'form-control' class is now needed.
Add new 'form-control' class to style header inputs
Add Bootstrap JS to make collapsible nav work

This example uses the collapsible nav for smaller screen sizes, and it
requires Bootstrap JS to get that functionality.

Fix grunt jshint
get jshint close to passing by updating .jshintrc settings

I don't agree with these personally, but they jive with BS/@fat's JS code style.
The remaining jshint complaints are things that really actually should get fixed.
