Title: GROOVY-6397: Prefix '\' to all commands

See https://jira.codehaus.org/browse/GROOVY-6397
Using backslash as command prefix because it is also used for single-letter commands. I don't like that choice too much, because on german keyboards the backslash is difficult to reach. But commands are probably not used that much anyway.
