Title: Fix to Issue #517: Cannot convert multipage PDFs to JPG with RMagick

This is a fix to the issue described in: https://github.com/jnicklas/carrierwave/issues/517

I added a spec under the processing_spec.rb file. It's just testing that converting a multi_page pdf with RMagick doesn't throw an error. The fix modifies the manipulate! method so that if it's called on a multi-page document without a block, it will return the raw list of frames without trying to call a non-existent block on them
