itsmattkc c168bf1a80 nodeparam: implemented parameters that allow arbitrary properties to be set
for UI representations

Allows properties to be set without adding explicit extra members to NodeInputs.
Crucially this means parameters like slider value representations (percent,
decibel, etc.) can be set from NodeInputs now.
