Issue: Adding a new parameter to a patcher with mapped parameters will change the mapping

[twhiston]

If you have a patcher and you map its parameters to midi and you then add a new parameter and re-export it, if the new parameter is inserted into the parameter list before the currently mapped parameters the existing mapping will change to the new parameter rather than respecting the old mappings. I guess this is some kind of parameter ID mismatch when the new parameter is added.
