[perl-win32-gui-hackers] additional fix for cursors

[Steve Pick]

In addition to Glenn Linderman's fix for resize cursors this should be put
in (@)INTERNAL:Create(%OPTIONS) near the top:

perlcs.hCursor = LoadCursor(NULL, IDC_ARROW);

I've put it just below the line that reads
perlcs.iEventModel = PERLWIN32GUI_EM_BYNAME;

This will stop the cursor remaining as a resize handle, hourglass etc when
moved inside the window.
