Improve the findfiles example: use QDirIterator, etc

It hasn't been necessary for a long time now to write the recursive
file-find function manually.  It has just been an obscurely documented
feature of QDirIterator for far too long.

Demonstrate the new QLocale::formattedDataSize() function.

Also sync up the qdoc description of this example with the recent changes.
