search & search_results routes/controllers as a replacement for shipments route/controller
removed old shipments code
amended sandbox shipments analogically to changes for main shipments
moved things around to better map views/templates to routes
slightly less scary loading modal
render shipment data cells using a component
more generic way of closing filter popups
handle the loading modal in the route
fixed fetching of current values of filters
fixed updating sandbox shipments
apparently we still need this for batch operations
remove duplication of tbody elements
got sick of not being able to see the total properly
removed unused properties
when resetting set the date range to default values rather than null
lame solution to issue with resetting the search form
Merge branch 'fix_trade_admin_home_page' into develop
