Integrate some QML examples and demos into qtdemo

Includes minor changes and additions to the existing doc and examples,
so that they follow Qt conventions better.

Note that while blurring the background was part of the plan for the
embedded QML viewer I could not get it to perform well enough. In the
future, when blur is fast enough (or someone else can get it to
perform better than I) -use-blur should become the default, and
-no-blur the option.

Task-number: QTBUG-10582

+With Qt Declarative, it is easy to implement the UI components that you need
+in exactly the way that you want. These examples demonstrate this by creating
+a selection of user interface components where the look and feel has been
+completely defined in a QML file.
+
+The example launcher provided with Qt can be used to explore each of the
+examples in this directory. But most can also be viewed directly with the
+QML viewer utility, without requiring compilation.
+
+Documentation for these examples can be found via the Tutorials and Examples
+link in the main Qt documentation.
+
+
+Finding the Qt Examples and Demos launcher
+==========================================
+
+On Windows:
+
+The launcher can be accessed via the Windows Start menu. Select the menu
+entry entitled "Qt Examples and Demos" entry in the submenu containing
+the Qt tools.
+
+On Mac OS X:
+
+For the binary distribution, the qtdemo executable is installed in the
+/Developer/Applications/Qt directory. For the source distribution, it is
+installed alongside the other Qt tools on the path specified when Qt is
+configured.
+
+On Unix/Linux:
+
+The qtdemo executable is installed alongside the other Qt tools on the path
+specified when Qt is configured.
+
+On all platforms:
+
+The source code for the launcher can be found in the demos/qtdemo directory
+in the Qt package. This example is built at the same time as the Qt libraries,
+tools, examples, and demonstrations.
