no PNG status support in nine

[dustin]

In eight, the PngStatusResource would return a PNG giving the current build status.

This class seems to be missing in nine, and greps for Png and PNG and so forth don't turn up anything that looks like a replacement.

This should at least be documented for 0.9.0.

As skelly suggest on irc, this is a good candidate for a plugin.

This bug for 0.9.0 is to document it is missing. Implementation can be done for 0.9.0+

#2109 is the documentation that is has to be done
