This patch fixes the watchcat init script in case of mode 'always'.
This mode just needs the config parameters: mode, period and forcedelay.
But a wrong check against the variable pingperiod, needed in the mode 'ping'
prevented mode 'always' to work properly.

Note that this implies an API change (allways -> always).
The wrong spelling "allways" is still accepted for backward compatibility.
