Use data binding instead of events where possible in searchlight-ui

The intersection of scope events, magic-search and smart table in searchlight-ui cause massive headaches when trying to make searchlight-ui do cool and interesting things.

Create better isolation between searchlight-ui components and an easier programming model by using data binding to set the available facets for magic search, to get the current search terms, to read current search settings.

Also, eliminate the dependency on "smart-table" which is excessively complicated way to display a simple table of search results.
