(svn r7356) -Codechange: replace 'for (i = 0, wi = w->widget; wi->type != WWT_LAST; i++, wi++)' type for loops with 'for (i = 0; i < w->window_count; i++) { wi = &w->widget[i];'-type for loops for better readability.

-Codechange: use IsWindowWidget(Disabled|Hidden) in favor of IsWidget(Disabled|Hidden).
