Go binding to ImageMagick's MagickWand C API

Go Imagick is a Go bind to ImageMagick's MagickWand C API.

It was originally developed and tested with ImageMagick 6.8.5-4, however most official Unix or Linux distributions use older versions (6.7.7, 6.8.0, etc) so some features in Go Imagick's master branch are being commented out and will see the light when these ImageMagick distributions could easily be updated (from the devops PoV).
