Now backspace and delete in text will select non-empty math and text insets before deleting them. This is consistent with what happens in math already. This is implemented for InsetText as well but can be disabled in case of negative feedback. This can be set for any sort of inset with the new virtual method Inset::confirmDeletion. New option "force" for the LFUN_*_DELETE_* commands, that bypasses the confirmDeletion check.
