[PD] Pd preferences dialog progress

[João Pais]

Looks very nice. Can you show also the other sections of the dialog?

One minimal detail: "Use single device" instead of "devices"

A bigger detail: does it make sense (for logical and practical reasons) to  
add a menu to select which channels go into which inputs/outpus, like on  
max/msp?
