Windows mobile client

Write a windows mobile frontend using the ppygui toolkit http://ppygui.sourceforge.net/ . Just a program to do the revisions should be enough. The amount of work to do this should be fairly limited, as most of the GUI indepent logic is moved to libmnemosyne. More specifically, you should implement the equivalent of pyqt_ui/review_wdgt, implementing the interface of libmnemosyne/review_widget
