Search functionality

Pluggable - some context service for indexing, search functionality in the navigation tree - default (node text) and custom - full text. Lunrjs implementation. Minisearch is also an option. One possibility is to add search configuration to Action, e.g. searchFields String->String map - this may have a problem with unavailability of all text because it may be generated or loaded at a later time. So, maybe scanning the generated pages, parsing them with Jsoup and extracting text from nsd-app-content-panel-content-row and title from nsd-app-content-panel-title or nsd-app-content-panel-title-and-items-row > col > h1 is the way to go. Generate search index and store it in the root similar to sitemap.xml. Perhaps ignore Javadoc initially.
