Updated MovieGrabber App

Changes since last pull request:
1. Fixed style and layout of index.erb (bootstrap)
2. Get full details of movie to play (and poster to display)
3. LOST save-to-database functionality for the time being

Following still needs work:
1. There should be a shared layout page (currently I need to add scrip/link at the top of all html erb pages...
2. Add style/layout to move result page
3. Additional style and layout changes
4. replace lorem ipsum text with actual directions
5. add functionality to the "save" button (save to db?)
6. implement additional tests
