[Koha] OAI datasets

[Steve Sowder]

I have discovered:

1. Tags used in mapping have to be indexed. Otherwise the SetSpec won't 
have anything in it.  This should be in the manual. Perhaps everyone 
just thinks "well everybody knows that". But it should be in the manual 
because not everyone knows.

2. Requesting a list with an invalid SetSpec (i.e. "joke") gives you all 
of the records. Same as no SetSpec at all. It probably should give an 
error.  No such "set".
