Properly document license of Qt examples

So far we only referenced
http://opensource.org/licenses/bsd-license.php,

which is actually not the BSD-3-clause license we use,
but BSD-2-clause.

While at it, also document the license itself as part
of the documentation, and reference it from the
licensing entry page.
