Adding crop capabilities to acts_as_attachment

Everyone know the plugin: acts_as_attachment created by Rick Olson , that let you manage file uploads and image resizing.
With a very little effort is possible to enhance this plugin by adding crop capabilities that will let you use the following sintax:
acts_as_attachment :thumbnails => { :thumb => 'crop 91x91'}
To achieve this goal you simply need to add 2 lines of code just after ‘instance_methods.rb’s row 133:
elsif size.is_a?(String) && size =~ /^crop ([0-9]+)x([0-9]+)$/i
img.crop_resized($1.to_i, $2.to_i)
Many thanks to Arya who suggested this patch.
