[gst-devel] changes to adder

I've been asked to explain my commits to adder, so here's the simple 

I think that adder should always send data, regardless of the fact if it 
has any input to it.  If it doesn't, it should send out zeroes, of course.
In my head, gst-launch adder ! osssrc should work, useless though it is in 
practical life.  Also, the same should work in gst-editor.

The reason I think this should work is that there are apps that will use 
adder, and connect and disconnect inputs to it as necessary.  Adder 
shouldn't stop working when all inputs are gone, and shouldn't wait to 
start working when none of it's inputs are connected.

I'm currently trying to get such a mixer app written, which is probably 
the direct reason for me trying to fix up adder in some places.

A prerequisite for that launch line to work is a way to set audio format 
properties on the cmd line - I guess this is what Andy objects to, though 
I'm not sure.
