Don't explicitly reference global jQuery

Removes `window.jQuery` in favor of `jQuery`, fixes #10038
Bower: Ignore development and documentation files on bower.json. Fix #10313.

I've kept only the files I consider relevant to bower installation:

- Files in dist directory;
- Files in js directory;
- Files in less directory;
- bower.json file;
- README.md file;
- LICENSE file.

Support .h1 in place of h1 inside .jumbotron

As in #7284, it can often be useful to style text like a heading in
places where using the heading tag would be either semantically
incorrect, less accessible, or otherwise invalid.

Support this in .jumbotron as in the rest of the document by allowing
elements with class .h1 to stand in for the h1 element.
