Spring Boot CLI "quiet" option doesn't silence the banner

[gregturn]

As shown here => https://github.com/spring-projects/spring-boot/blob/v1.4.0.RELEASE/spring-boot-cli/src/main/java/org/springframework/boot/cli/command/run/RunCommand.java#L141-L150

The CLI DOES properly suppress all logging. However, it still prints out a banner to the screen, making it unsuitable for UNIX-y style scripts.

$ spring version
Spring CLI v1.4.0.RELEASE
$ spring run -q /usr/local/bin/bootconsole.groovy < ~/Dropbox/Greg/learning-spring-boot-2nd-edition/1/fragment_01.txt

(the rest of that example script is output that is expected)
