Edits for clarity, grammar, spelling, usage.
Add metadata about the QMake and CMake packages installed by this framework and remove Links from README.md
Shorter lines for the book snippets.
Started a new example based on SequenceDemo that will be way better :-)
Rigging for the asynchroneous operations.
Load the background image asynchroneously.

Make it last a bit longer by sleeping a second.
Implement downloading the post.
Implemented the two download steps.
Visual fixes.
Final touches (show the post URL, layout).
Formatting for code snippets and simplicity.

For code snippets, the lines should be about 60 characters wide, not
much longer. 60 characters seems to be a good compromise on eBook
readers and for PDF.
