Usage of `silencer:globalFilters` in Maven projects.

See original GitHub issue

How can we use silencer:globalFilters in maven projects?

-P:silencer:globalFilters=<semicolon separated message regexes>

I am trying to pass the silencer flag option using scala-maven-plugin

<configuration>
<args>
<arg>-P:silencer:globalFilters=Unused import</arg>
<arg> ....<arg>
<arg>-Xfatal-warnings</arg>
<arg>-Ywarn-unused-import</arg>
</args>
</configuration>

Yes, that solves that issue. Thank you @jozic @SethTisue. Perhaps it is better to add these instructions to the README.
