Make basicsuite demos run stand-alone

This change will make the demos run standalone when built in
Qt Creator.
    - Rename example directories to lowercase/non-whitespace
      to avoid build & deployment problems
    - Add title.txt files so titles remain displayed correctly
      in the launcher
    - Add a common shared source files used for the standalone
      apps, and .pro-files for each example
    - Remove .qmlproject files (not needed)
    - Adjust documentation to match the new directory structure
