wxwidgets 2.8 breaks compatiblity with 2.4 series unless compiled with special flags (most common distros doesn't use such option)

we can either drop 2.4 compatibility (wich is more than 2 years old & i would recomend) or wrap the depricated code in #ifdef

wxnotebooksizer is depricated since wx2.6, instead any other sizer would do the same task

fix for 2.8 compatibility

Thanks BD added to CVS.
