Improper console output if no service name could be found

[Joerg Mattiello]

When invoking the monit command line with start, stop or the (un) monitor option, monit prints some additional improper text at the end

# monit start ZZZ
Action failed -- There is no service named "ZZZ"<hr><a href='http://mmonit.com/monit/'><font size=-1>monit 5.12.2</font></a></body></html>

Fixed: Issue #179: If the CLI command failed, the output may contain HTML footer in addition to plaintext error description.
