[Codelite-developers] patch for using Page down and Page up in autocomplete box

[Rodrigo G. <rjg...@gm...>]

This patch just move 10 items back or after current selected item when 
pressing page down or page up.

The only "bad" thing is that 10 is a magic number, I don't know how to 
know how many items are shown in the listbox.

Thanks

Rodrigo
