Fix wxHMI example after upgrading wxGlade
Newer wxGlade generates code to initialize GridSizer's with empty
elements.
...
grid_sizer_1.Add(self.window_1, 1, wx.ALIGN_CENTER, 0)
sizer_2.Add((0, 0), 0, 0, 0)
sizer_2.Add((0, 0), 0, 0, 0)
sizer_2.Add((0, 0), 0, 0, 0)
sizer_2.Add((0, 0), 0, 0, 0)
...
That causes following traceback, if new buttons are added
to already full sizer.
PLCobject : Traceback (most recent call last):

../src/common/sizer.cpp(1401) in DoInsert(): too many items (11 > 2*5)

columns?)
Tested with wxGlade version 0.8.3
