init.d scripts for linux, updated runclient.sh

[smith.js.8 at pg.com]

For general consumption, and to give back a little...

I'm running hobbit on several linux servers, most of them Red Hat or 
variants thereof. Following are the scripts I use to start/stop the hobbit 
server and client.

You'll need to modify the locations for pidfile and config in the script 
header comments, plus the values for BBUSER and BBINIT in the scripts 
themselves.

These are chkconfig friendly scripts. If you're using chkconfig, after 
creating the files you should:

# chkconfig --add hobbitd
# chkconfig hobbitd on
# chkconfig --list hobbitd

# chkconfig --add hobbitc
# chkconfig hobbitc on
# chkconfig --list hobbitc

Then you can use the 'service' command to control hobbit. See these 
commands for options:

# service hobbitd help

# service hobbitc help

I've also attached a modified runclient.sh that adds 'restart' and 
'status' options.

Henrik, please feel free to massage these as necessary (for example, so 
the configure/make commands fill in the necessary blanks) and include them 
in the snapshots/packages. In the code below I've use {UPPER_CASE} to 
indicate areas that need to be changed before use on a user's systems.
