Change field searches to use fields instead of handlers

[ruebot]

If we do something similar to what @anjackson did in this commit, we'd leave less of a burden on the implementer to setup a custom solrconfig.xml like we ship here, and if they already have a Solr index two setup with the same or similar schema.xml that webarchive-discovery ships, it would be an easier drop-in.

warclight/lib/generators/warclight/templates/catalog_controller.rb

Lines 120 to 134 in ef0c872

	config.add_search_field 'title', label: 'Title' do |field|
	field.qt = 'title_search'
	end
	config.add_search_field 'content', label: 'Content' do |field|
	field.qt = 'content_search'
	end
	config.add_search_field 'url', label: 'URL' do |field|
	field.qt = 'url_search'
	end
	config.add_search_field 'host', label: 'Host' do |field|
	field.qt = 'host_search'
	end

Less things to maintain?

@anjackson @ianmilligan1 let me know what you think.

I'm far from a Solr expert, so I'd defer to you and @anjackson, but going down this route makes perfect sense to me!

After some good discussion in IIPC webarchive-discovery channel, I'm going to move forward with this. It'll make Warclight easier to implement for webarchive-discovery users.
