Upgrade to pngnq-s9 2.0.1

[joeyhoer]

The current pngnq has the following version information:

pngnq 1.1
   Compiled with libpng 1.5.14; using libpng 1.5.14.
   Compiled with zlib 1.2.5; using zlib 1.2.5.

However the ImageAlpha website claims "ImageAlpha can achieve better quality … by employing … pngnq-s9", despite the fact that the bundled binary identifies itself as:

pngnq 1.4.5
   Compiled with libpng 1.4.5-optipng; using libpng 1.4.5-optipng.
   Compiled with zlib 1.2.5; using zlib 1.2.3-optipng.

I was unable to locate this version online and assume it to be an outdated version of pngnq-s9 as indicated on the project homepage.

While I was also unable to successfully compile the latest version of pngnq-s9 (currently 2.0.1) on OS 10.9, I would like to suggest the project be updated with the latest version.

pngnq is up to date, it's just showing libpng version instead of its own.

I finally did get it to compile. The version that I compiled from source prints:

pngnq 2.0.1
   Compiled with libpng 1.5.14; using libpng 1.5.14.
   Compiled with zlib 1.2.5; using zlib 1.2.5.

I'm assuming theres something different between the version included with ImageAlpha and the version I compiled from source, although there doesn't appear to be any additional functionality. I believe you when you say it's the same, I'm just curious as to what the differences could be. The version I compiled is also approx. 72KB as compared to the 62KB pngnq included in ImageAlpha.
