Update examples documentation location

The current way of documenting examples is to include
qdoc and images source into example directory.
Fix examples in location and positioning.
Replace planespotter.jpg with png.

+    \example weatherinfo
+    \title Weather Info (C++/QML)
+
+    \brief The Weather Info example shows how to use the user's current position
+           to retrieve local content from a web service in a C++ plugin for QML.
+
+    \ingroup qtpositioning-examples
+
+    Key \l{Qt Positioning} classes used in this example:
+
+    \list
+    \li \l{QGeoPositionInfo}
+    \li \l{QGeoPositionInfoSource}
+    \endlist
+
+    \image ../images/example-weatherinfo.png
+
+    \include examples-run.qdocinc
+
+    The example uses weather data provided by \l http://www.openweathermap.org.
+
+    The key part of this example is the application's data model, contained
+    in the WeatherData and AppModel classes. WeatherData represents the weather
+    information taken from the HTTP service. It is a simple data class, but we
+    give it Q_PROPERTies to expose it nicely to QML, later.
+
+    \snippet weatherinfo/appmodel.h 0
+    \snippet weatherinfo/appmodel.h 1
+
+    AppModel models the state of the entire application. At startup, the
+    application first begins by waiting for network connectivity. We do
+    this using the QNetworkConfigurationManager and QNetworkSession family
+    of C++ APIs.
+
+    \snippet weatherinfo/appmodel.cpp 0
+    \snippet weatherinfo/appmodel.cpp 1
+
+    Once the network session is open, we proceed to get the platform's
+    default position source using QGeoPositionInfo::createDefaultSource()
+
+    \snippet weatherinfo/appmodel.cpp 2
+
+    If no default source is available, we take a static position and fetch
+    weather for that. If, however, we do have a position source, we connect
+    its positionUpdated() signal to a slot on the AppModel and call
+    startUpdates(), which begins regular updates of device position.
+
+    When a position update is received, we use the longitude and latitude
+    of the returned coordinate to retrieve the current "city" name for use
+    in the weather lookup.
+
+    \snippet weatherinfo/appmodel.cpp 3
+
+    To inform the UI about this process, the cityChanged() signal is emitted
+    when a new city is used, and the weatherChanged() signal whenever a
+    weather update occurs.
+
+    \snippet weatherinfo/appmodel.h 2
+    \snippet weatherinfo/appmodel.h 3
+    \snippet weatherinfo/appmodel.h 4
+
+    We use a QQmlListProperty for the weather forecast information,
+    which contains the next 4 days of forecast weather. This makes it
+    easy to access from QML.
+
+    To expose these to the QML UI layer, we use the qmlRegisterType()
+    function. We call this once for each type we wish to register, before
+    loading the actual QML file.
+
+    \snippet weatherinfo/main.cpp 0
+    \snippet weatherinfo/main.cpp 1
+
+    Finally, in the actual QML, we instantiate the AppModel.
+
+    \snippet weatherinfo/weatherinfo.qml 0
+    \snippet weatherinfo/weatherinfo.qml 1
+    \snippet weatherinfo/weatherinfo.qml 2
+
+    Once instantiated like this, we can use its properties elsewhere in the
+    QML document:
+
+    \snippet weatherinfo/weatherinfo.qml 3
+    \snippet weatherinfo/weatherinfo.qml 4
