Rescale Oxygen-derived icons to 256x256

These higher-resolution images improve the appearance of some of the
icons Anki ships with, particularly when seen from the operating system.
aqt.util.tooltip(): use old help-hint.png size

Because this is actually an HTML-based overlay, it was mishandling a
higher resolution image and not scaling it down.

My initial thought for this was to specify width/height attributes on
it, but that made the image look really crummy (possibly because it is
not Qt proper).

This change puts back in the 32px version of the image, just for this
overlay.
