Updated _all_ plugins so that initGui() is implemented as a slot.
This is required if you wish to use qgsproject for storing and reinstating state in qgis. The reason for this is that the initGui() method is only called once at the moment when qgis starts up. I will be adding a signal to qgisproject 'projectLoaded' that will be emitted when a new project is loaded. I will also be adding connect() for each plugin when its initially loaded in qgisapp so that the initgui slot is called whenever the project loads.

must now have a QAction member pointer that is created when the GUI is
initialized in initGui(). This pointer is used in the unload() method to
remove the QAction and associated icon from the plugins toolbar.
* Updated splash for upcoming 0.5 release
