Merge wxQT branch into the trunk.

This merges in the latest sources from GSoC 2014 wxQt project with just a few
minor corrections, mostly undoing wrong changes to common files in that branch
(results of a previous bad merge?) and getting rid of whitespace-only changes.
Also remove debug logging from wxGrid.

+/* wxQt specific notes:
+ *
+ * Remember to implement the Qt object getters on all subclasses:
+ *  - GetHandle() returns the Qt object
+ *  - QtGetScrollBarsContainer() returns the widget where scrollbars are placed
+ * For example, for wxFrame, GetHandle() is the QMainWindow,
+ * QtGetScrollBarsContainer() is the central widget and QtGetContainer() is a widget
+ * in a layout inside the central widget that also contains the scrollbars.
+ * Return 0 from QtGetScrollBarsContainer() to disable SetScrollBar() and friends
+ * for wxWindow subclasses.
+ *
+ *
+ * Event handling is achieved by using the template class wxQtEventForwarder
+ * found in winevent_qt.(h|cpp) to send all Qt events here to QtHandleXXXEvent()
+ * methods. All these methods receive the Qt event and the handler. This is
+ * done because events of the containers (the scrolled part of the window) are
+ * sent to the same wxWindow instance, that must be able to differenciate them
+ * as some events need different handling (paintEvent) depending on that.
+ * We pass the QWidget pointer to all event handlers for consistency.
