Initial rspec/capybara feature tests for query interface.
Added Capybara feature tests for query interface.

1. Used capybara-webkit as the js driver, because the selenium-webdriver
was causingthe first test to fail (tests run randomly, was always the
first test executed that failed).
Added additional sort test.
Forgot an .each on Capybara tests. Was skipping a block.
Removed comment from collection.js :
Removed MONGO_TEST_DB constant, test database is set automatically in
config/mongo.yml
Removed selenium-webdriver.
Set webkit as default capybara js driver.
