Bugfix for wrong UIPopupList drop-down colliders

[veblush]

Hello, there.

With NGUI 3.6.5, UIPopupList may generate wrong sized colliders for drop-down list items.
Even though UIPopupList.OnClick() works well for calculating size of collider,
NGUITools.AddWidgetCollider set autoResizeBoxCollider true and makes size fit with contents of item. (padding size missed!)

I've just fixed this bug as following.
Please consider it for next release.

Thanks, I will add your change.

This fix messes UIPopupList up in other situations. I am using UIPopupList in conjunction with a uiInput as autocompletion suggestions.

For me it requires this additional fix, but im unsure wether it works for other situations as well:

change line 850 in UIPopupList.cs:
         Vector3 bcCenter = new Vector3(cx * 0.5f, -fontHeight * 0.5f, 0f);

to:
         Vector3 bcCenter = new Vector3(cx * 0.5f, -labelHeight * 0.5f, 0f);

I'll change it and see if it breaks anything on my end.
