Remap effect type from "Audacity" to "Built-in", carefully...

... doing that only for the user-visible string, seen in the Manage>About menu
of the effect dialog and in the sorted or grouped Effect/Generate/Analyze
menus.

But don't for the string used internally and written into pluginregistry.cfg,
so that compatibility of that file is preserved.
