Remove pubsub functionality

Hilib's pubsub works on the global Backbone object. Multiple FS
instances would share Backbone and thus listen to eachothers pubsub
messages. To avoid this we removed all pubsub, this means removing
(hilib) baseView, baseModel and baseCollection. This also means we have
to listen to FS 'unauthorised' event, because it is no longer directly
published using the Backbone object.
Config params changed
Hardcoded VRE_ID header to query DutchCaribbean data
Removed default sort: null, as it's not supported by Timbuctoo (yet)
Add check if searchResults > 1, only then update
Ignore stage/compiled
Turn on livereload
