Qt Charts project file structure change

Charts repository structure is changed to follow the structure of a
Qt Add-On module. The task includes following changes:

- All macros and definitions named 'commercial' have been renamed.
- Compile errors related to QString and qSort usage have been fixed.
- Old demos are moved under examples. The QML examples now support only
  Qt Quick 2.0, the support for Qt Quick 1 is removed.
- The QML examples with multiple views are updated so that they are
  usable also with touch devices.
- Unnecessary version checks are removed from examples.
- The build stamp has been removed as it was only meant for Charts
  development purposes and it's no longer needed. Also development
  build related debug prints are removed as __DATE__ can't be used
  for all OS thus it doesn't make much sense.
- Documentation structure has been updated based on the new module
  structure. The raw HTML files have been removed. Demos are
  combined to examples.
- Unnecessary .qdocinc files are no longer needed. The content is
  moved to the corresponding .cpp files.
- The Charts widget designer plugin is updated according to the module
  change.
- The test cases updated according to the project structure change.
  Tests are added also for version 2.0.
- cmake modules generation is not needed with Qt 5.4 and Qt Charts
  so it's disabled.
- The new module name and version are updated to the plugin.qmltypes
  file.

+     \example donutbreakdown
+     \title Donut chart breakdown example
+     \ingroup qtcharts_examples
+
+     \brief This example shows how to use create a donut breakdown chart using QPieSeries API.
+     \image examples_donutbreakdown.png
+
+     Let's start by defining some data for the chart.
+
+     \snippet donutbreakdown/main.cpp 1
+
+     Then we create a chart where we add the data. Note that this is our own chart derived from QChart.
+
+     \snippet donutbreakdown/main.cpp 2
+
+     Our own chart works in such a way that we create a main series in the constructor we create a main series,
+     which aggregates the data provided by the breakdown series. This is the piechart in the center.
+
+     \snippet donutbreakdown/donutbreakdownchart.cpp 1
+
+     When a breakdown series is added the data is used to create a slice in the main series and the
+     breakdown series itself is used to create a segment of a donut positioned so that it is aligned
+     with the corresponding slice in the main series.
+
+     \snippet donutbreakdown/donutbreakdownchart.cpp 2
+
+     Here's how the start and end angles for the donut segments are calculated.
+
+     \snippet donutbreakdown/donutbreakdownchart.cpp 3
+
+     The legend markers are customized to show the breakdown percentage. The markers for the main level slices are hidden.
+
+     \snippet donutbreakdown/donutbreakdownchart.cpp 4
+
+     Instead the main level slices show the percentage on the label.
+
+     \snippet donutbreakdown/mainslice.cpp 1
+     \snippet donutbreakdown/mainslice.cpp 2
+
+     Now that we have our chart defined, we can finally create a QChartView and show the chart.
+
+     \snippet donutbreakdown/main.cpp 3
