Subject: Export gamma setting and metadata in QImageReader

The PNG image plugin has the capability of applying gamma correction
to read PNGs, but doesn't do so by default, and we export no way of
accessing this through the qimagereader API.

This patch adds the ability to read the PNG file gamma, and overriding
decoded gamma to get gamma correction.
