would be nice if trader Lamas had a config for Their ability

Actually, you can already add it to the config, but yeah, I'll add it to the default config, too.

Implemented as of e0deb37. Now, if you're morphed as any possible mob, the entity will be automatically added to the config with the default value, if it's not present (as of ee85175).
