Add option for dynamic layer names when using nested Unify plugins

This is just a small quality of life thing, but when you have a bunch of Unify layers set to various patches inside a main Unify instance it would be super cool if you could have it auto update the layer name based on the currently selected patch inside the Unity plugin for each layer. I am especially thinking of mulititimbral setups where you might be changing patches based on MIDI messages and it can get hard to keep track of your configuration when all the layers are just called INST 1 to INST 16. Basically copy the title text into the layer name field of the outer Unify instance.
