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 accelerators implementation:
+ *
+ * Storing:
+ * QShortcuts are stored in wxWindow (m_qtShortcuts) to allow to delete them
+ * when the accelerator table is changed, and also because we need to specify
+ * a not-null parent from them, which is unknown at the moment of creating the
+ * accelerator table. So, the accelerator table only contains a list of
+ * wxAcceleratorEntries, which are converted to a list of QShortcuts when
+ * the table is fixed to a wxWindow.
+ *
+ * Passing keypresses to accelerators:
+ * The accelerators are implemented using QShortcut's. As there is no easy way
+ * to call them, we must pass all keypress events through the QApplication
+ * notify() function (which is the one that checks if the keypress match any
+ * shortcut.
+ *
+ * Executing commands when a QShortcut is triggered:
+ * Each QShortcut has a property ("wxQt_Command") set with the number of the
+ * wx command it is associated to. Then, its activated() signal is connected to
+ * a small handler (wxQtShortcutHandler in window_qt.h) which calls the main
+ * handler (wxWindow::QtHandleShortcut) passing the command extracted from the
+ * QShortcut. This handler will finally create and send the appropriate wx
+ * event to the window. */
