should ignore .idea (RubyMine) project
need ci_reporter for junit style rspec reports - consumable by jenkins

* needed to roll back to 'rspec-rails', '~> 2.14.2' from '3.0.0'
  because ci_reporter does not support 3.0.0
rake task for generating junit results from rspec

$ bundle exec rspec spec GENERATE_REPORTS=true
updated README with ci information
trigger ci pr build

/rspec/core/configuration.rb:896:in `load': cannot load such file --
   /vagrant/GENERATE_REPORTS=true
whitespace change to trigger CI
repositioning report dir and changing how rake task is called on ci

* it is not safe to write to spec/reports - what if you wanted a spec
  directory named 'reports'?
* GENERATE_REPORTS does not work on vagrant
Merge pull request #4 from wetap/feature/rspec-reports-junit
