first green test with phantomcss. #1
move reference screenshots to test folder. #1
force failed test. #1

- failed screenshots folder is in base directory. that way a git status will output a list with failed test diff images
get tests back to green. #1

- without any more setup, fail screenshots need to be manually removed from failure/ and test/visual/screenshots
- an automated setup in grunt should clean up failures when tests are back to  green.
- a watch task for the failures folder could open an interface where you approve a failed test image as still passing or mark a new master (which should trigger the tests again). see csscritic.
move failures. set up git to show failed tests. #1

- screenshot folder is now ignored by git
- failures folder moved to test directory and is not ignored.
- that way failed tests show up as untracked files in git status.
