Initial commit for context UI
Update context mock to match Serrano changes

Update ContextNode view to correctly parse and flatten the language
text for nested nodes.
Merge branch 'thin-client' into query-filters
Add EmptyView for consistent styling with loader option
Fix unwrapped Bootstrap, fix missing jQuery reference in Highcharts
Update empty view
Remove options object initialization prior to _.extend

_.extend ignores null/undefined arguments
Fix chart options parsing

Rename unclear options.options => options.chart
Perform a reset on queryable and viewable collections

Remove condition to ignore models without a `queryview`. This was a
previous behavior that is not longer. Collections passed into the
ConceptIndex are expected to be pre-filtered.
