mini_magick 1.2.1

- Why? I was using RMagick and loving it, but it was eating up huge amounts of memory. A simple script like this... Magick::read("image.jpg") do |f| f.write("manipulated.jpg") end ...would use over 100 Megs of Ram. On my local machine this wasn't a problem, but on my hosting server the ruby apps would crash because of their 100 Meg memory limit.
