Foundations for a test suite

[mksndz]

We need to add a test suite to this app. The prudent place to start is with feature specs that will test all aspects of the application. Before we can start writing specs, we need:

• install & configure rspec and capybara
• figure out & configure a headless browser configuration to allow our javascripty behaviour to be tested. see apparition?
• figure out a way to run solr in a testing environment. a docker container with solr might do and work well with out ci setup. sample data will also need to be indexed on each run.
