v0.2.2

v0.2.2 release branch

page layout also used out of the box by Jekyll

Improve search data generation

Because `page.title` (and `page.url`) is already escaped and page titles served by lunrjs do not need escaping, ampersands need to be unescaped to display properly in search results.

and mention `search_exclude`

Suggesting page, since `about.md` uses it for new Jekyll installs as well.

Documentation cleanup

For pages in utilities/, reorder `nav_order` to follow `parent`.
