Log Level should be adjustable on plugin level

[ghost]

Hi,

Could you please add an option to mute or reduce the log output of the minify-maven-plugin?

It currently creates 3 lines of log entries per JS file, e.g.

[INFO] Creating the minified file [Formatter.js].
[INFO] Uncompressed size: 1365 bytes.
[INFO] Compressed size: 526 bytes minified (259 bytes gzipped).

This is a matter of optimisation for us as we slowly lose overview of what's actually relevant in our logs. I do not see, how any of the logged information could be of use when logged for each single file in every single build.

Thanks
