Summary:                    SPEECH_ENGINE should be readable

restore the old value.  But you can't current read it.

---------------------------------------------------------------------- 
Let's suppose there's a parameter named foo and I want to modify it for one
particular SpeechBackground call to have a value of 7 and then restore the
previous value.  So what I'd like to do is:

exten => s,n,Set(save_foo=${SPEECH_ENGINE(foo)})
exten => s,n,Set(SPEECH_ENGINE(foo)=7)
exten => s,n,SpeechBackground ...
exten => s,n,Set(SPEECH_ENGINE(foo)=${save_foo})

I can't do this now but instead have to KNOW what the original value was. 
But that value is likely in some other config file which means that if I
change it later, I have two places to change.  That's bad.
