fixes to get AW compile and run on win32. Had to move the call to pDocLayout->fillLayouts() in ap_Win32Frame.cpp::_showDocument() immediately after the view allocation, and similar change will probably be required on other platforms.
also a fix to PgUp/Down behaviour files: fl_BlockLayout.h, ap_Win32Frame.h/cpp, gr_Win32Graphics.cpp/h, ev_Win32Toolbar.cpp, fl_DocLayout.cpp, fv_View.cpp Tomas
