Title: Suppress the compression output of individual files

I'm working with a large project, few hundreds images and I'm not really interested in logging every single file.

With this PR it's possible to set `silent: true` and send all those messages to `grunt.verbose` instead of `grunt.log`.
The total summary is still logged.
