On the switch, there is no need for the ppsi to use config file in
the /wr/etc/ppsi.conf.

Due to a bug in lib/conf.c, the conf file must be ended with a newline char;
if not, the latest line is ignored. The bug will be hopefully solved soon,
in the meantime this simple workaround avoids any problem.

The ppsi.conf file will define the basic behaviour of ppsi, prior to cmdline
options, which will override conf settings. Here a sample ppsi.conf is
defined, where a mini-switch, driving two slaves, is configured.
User will need to define their own ppsi.conf according to their needs.
