[Koha] Deleted preinstalled authority types

[Rubén Fernández Asensio]

Hello,
I think the title says it all. I'm planning on using only Personal name 
authorities, so I tried to delete the others. Now I find errors when I 
run the MARC bibliographic framework test:

invalid authority types 	Not all authority types referred to by the 
frameworks are defined.
Framework code 	Framework description 	Etiqueta 	Subfield 	Invalid 
authority type
	Default framework 	648 	a 	CHRON_TERM
	Default framework 	650 	a 	TOPIC_TERM
	Default framework 	651 	a 	GEOGR_NAME
	Default framework 	654 	a 	TOPIC_TERM
	Default framework 	656 	a 	TOPIC_TERM
	Default framework 	657 	a 	TOPIC_TERM
	Default framework 	658 	a 	TOPIC_TERM
	Default framework 	662 	a 	GEOGR_NAME
	Default framework 	690 	a 	TOPIC_TERM
	Default framework 	691 	a 	GEOGR_NAME

I assume if I edit the Default framework I'll botch my Koha installation 
even more. How can I recreate the deleted types?
Also, is there any way of hiding unused authority types from the user's 
authority search interface?

Thanks,
Ruben
