No colorization when batch mode and file logging are misinterpreted

[jcgay]

mvn dependency:tree -Dincludes="commons-logging" deactivate colors because activation is reading environment variable MAVEN_CMD_LINE_ARGS and use contains to decide if the -l parameter has been used.

It should split MAVEN_CMD_LINE_ARGS content on space (and probably on equals sign) and test the fragment exactly!
