Site search and Bidders updates

[bookwyrm]

Adds doc search to the site via Algolia.
Restructures Bidders page to add autocomplete support and updated design that groups bidders by name.

Includes a helper script (find-ungrouped-bidders.sh) to verify that all Bidders have been assigned to a list_group for proper display on the Bidders page.

@bookwyrm - thanks, but I'm not real fond of the new 'list_group' header value. These values are set and maintained by hundreds of different companies, and they will certainly screw them up. It will end up adding a bunch of error-prone work on the part of the doc reviewers... we're going to have to A) remember to make sure it's there and B) keep a list of the valid values.

Is there no way to automate this grouping another way? How about this:

{% assign bidder_pages = site.pages | where: "layout", "bidder" | where: "pbjs", true %}

/* 0 and a */
{% for page in bidder_pages %}
    {% assign firstletter = page | slice:0 | downcase %}
    {% unless firstletter == "0" or  firstletter == "a" %}{% continue %}{% endunless %}
    ... do stuff ...
{% endfor %}

/* b and c */
{% for page in bidder_pages %}
    {% assign firstletter = page | slice:0 | downcase %}
    {% unless firstletter == "b" or  firstletter == "c" %}{% continue %}{% endunless %}
    ... do stuff ...
{% endfor %}

Thanks, @bretg. This is a much better approach.
