Add jasmine gem with phantonjs continuous integration tests

Remove jasminerice - not compatible with rails 4
jasmine installed with rails generator
Includes default spec, helper, and config files
Add jasmine tests SearchBox function

Test coverage:
- #preparedArtistQuery
- #parseArtistInfo
Fix spelling error SearchBox method getArtistInfo

- Previously name getAristInfo in application_controller.js and search_box.js
Complete jasmine SearchBox unit tests

- Edit jasmine.yml - testing suite includes all files except application_controller.js which was conflicting because of the freebase method call ".suggest()"
- Add stub seatgeek data - returned json object from ajax call and parsed artist object returned from SearchBox.parseArtistInfo
