Make check_ide_smart default to nagios output

check_ide_smart was originally a smard control utility later converted
to a monitoring plugin. the -n option (Nagios check) should therefore be
the default.

This patch deprecates the -n and -q switches, and make the other
switches return nagios-compatible output (they are most likely used in
eventhandlers, but returning nagios-compatible output makes it clear and
easy to handle the return status)

 	WARNINGS
 	check_procs now ignores its parent process to avoid unexpected results when invoked via certain shells
 	utils.sh no longer defines ECHO
+	check_ide_smart -q (quiet) and -n (Nagios-compatile output) are now deprecated
