Title: Restore compatibility with GraphicsMagick.

Commit 302aaa3b added the -quiet option on
identify commands. This broke compatibility with
GraphicsMagick as there is no such option for
their implementation identify. It may make more
sense to put in the mini_gmagick file but here's
the quick fix.

This is a squashed version of pull request #66. I created a different branch/pull-request as others may be using the current one via bundler so it wouldn't be smart to mess with the history.
