Net_Gearman update

[Joe Stump]

All,

It's been a while since I've updated the list on the status of the PHP  
PEAR package Net_Gearman. Chris and I have been working on adding lots  
of enhancements and are preparing it to be included in the official  
PEAR project. For now, all of the code and the current release of the  
PEAR package can be found at Google Code (http://code.google.com/p/netgearman/ 
).

The latest commit includes Net_Gearman_Manager that lets you get  
stats, information, version, etc. from Gearman servers. It also lets  
you gracefully shut down Gearman (via the "shutdown" command). I think  
this class will be great for those who want to wait for the queue to  
be clear before shutting down workers, etc.
