authentification bugfix :

authentification bugfix :
the api in pod-auth.pm has "type => 'opac' "parameter.
If called from intranet, should be type => 'intranet'.
Output.pm checked for type existed, and not it's value. Now, Output compares checks for type value.
If type='intranet', then the intranet template is called, else it's an opac template.
Finlay, please validate this commit.
