Some simple fixes to failing tests.
Merge branch 'development' into rb/379-admin-interface-digitizations.

Travis is whining about 100+ failed tests, so attempting to fix that.
Changes how basic http auth is set up. Now checks for environment variables.
Monkey patches ActiveRecord to cause Capybara to share db connection so that transactional fixtures can be turned on with RSpec, eliminating need for DatabseCleaner to run in after(:each) or after(:context) hooks.
NOTE: DatabaseCleaner is still used to truncate db in before(:suite) hook.
