    Filter zinc compilation warnings at the Reporter level
    
    The existing impl did not include the severity in its match, so it's possible that errors could be filtered.
    
    - Only filter non-errors
    - Filter zinc compilation at the Reporter level, rather than in the logger
    - Split between message filters and filename filters
    
    Testing Done:
    Used:
    
        ./pants --config-override=pants.ini.isolated publish.jar --no-dryrun --local=~/.m2/repository --named-snapshot=$USER-`date +%s` src/scala/org/pantsbuild/zinc::
    
    ...to do a local publish, then tested that:
    
        ./pants --config-override=pants.ini.isolated compile testprojects/src/java/org/pantsbuild/testproject/dummies::
    
    properly applied both `-msg-filter` and `-file-filter`.
    
    ----
    
    Can add a pants integration test once this release goes out.
