starting code for current user showable search results, based on affiliation
refactored the filter code
removed student/alumnus privacy as they will not be indexed if privacy is true

Merge branch 'master' into user_affiliation_filter

Conflicts:
	app/controllers/searches_controller.rb
updated test settings for elasticsearch environment so that it uses the correct index
Cleaned up tests

We need to allow elasticsearch requests to webmock. Only log
elasticsearch requests in development.

Added newlines at the end of all the new files.
