phpCA client

[Justin]

Yeah yeah yeah... But I don't see myself ever wanting to do that. 

Here's another solution; these are regular functions, not enclosed in a
class.  Use get_multi.  I forgot I had written this a few weeks ago,
removing that !FALSE!/!TRUE! code.  I think the API should ultimately return
a NULL if the value doesn't exist, but this is a good way around it until we
can all finalize on a single API that works.  :)
