Custom fixture type label strings for new fixture type labeling system

The new fixture type labeling system has multiple fields to add some more structured metadata for fixture types.  The problem with this is that the console now decides how to use these fields to label fixture types, which can clash with existing user labeling schemes.  For example, I almost always label fixture types as "[Manufacturer] [Model] - [Mode]."  "Martin MAC Viper Performance - Ext", "GLP Impression X5 - M2", etc.

If I want to keep this naming scheme with the new system, I essentially have to intentionally use it incorrectly.  It would be helpful to be able to customize how these fields are used in the fixture type label.
