Made screen and print versions of the effects tutorial.

This is a rather dirty hack, and the screen version is not intended to look preety just be better suited to screen viewing.

| Attribute | Screen     | Print         |
|-----------|------------|---------------|
| Page Size | 9in X 6in  | a4paper       |
| Margins   | 0.5in      | fullpage      |
| Listings  | breaklines | no breaklines |

The 9in X 6in size for screen is Memoir Class's recommendation for eBooks.
Fixed problems with spacing in code environments
Updated to reflect current version of effects.
Fix up regarding bookmarks.
