Renaming factory amps and effects

[DiffractionCircuit]

There is already a request for this.

Rename units

Allow users to rename models, effects, and other units. I am sure that most users want to see Gibson EH-185 or Bogner Uberschall on the list instead of the ridiculous Gibtone 185 and BomberUber. Many probably would like to add their own mark in the name like “boring”, “power!”, “higain". Since copywriters in their madness go to extremes, let them try to demand something from end users of the product. In war all means are good.
