Don't Lock Noitd If Only Reading Stuff From Config

If a user is utilizing the "-x" option to pull values from
the config files, we don't need to acquire the lock. Only lock
if we actually need to acquire the process lock.
Add Ability To Send To Multiple Jezebel Processes

Changed the configuration for Jezebel to support sending to
multiple Jezebel processes by specifying multiple URLs in the
config file. Removed the "port" config option, since it was
never used.
Spawn Jezebels For All Local Ports In Config File

Modified the Jezebel start wrapper script to read the contents of the
configuration file, determine all Jezebel processes that are supposed

of just spawning one on the default port.
Add More Configurability/Versatility To Jezebel Wrapper

Made two changes to the Jezebel wrapper script:

1) Modify the xpath to catch the Jezebel path if it's not enclosed
   in a "Lua" XML element.
2) Allow specifying a config file to the script that will override
   the default config file the script looks for.
Spawn Default-Port Jezebel If No Ports Found

If we can't find any ports to run on in the config file, run on
the default port.
