Changeset 229 for lm-sensors/trunk/prog/daemon

(Phil) Added my little daemon program. For the record, here's some
features of it:

- As long as the 'sensors' program works correctly, healthd.sh is compatible

with any hardware.

- Very low loading. Just sleeps (like me) most of the time.

- Easily customizable (very simple and short script).

Todo's/wants:

- Syslogging? I couldn't figure out how to syslog from bash shell (yet).

- After one test, it failed to be automatically 'spawned' from a rc.local

script. I did "healthd.sh &", but that didn't seem to work. Ideas?

- a history utility for making pretty plots and such.

- Written in 'C' for better functionality and efficiency?
