sqlite: Implemented needed functions to enable authentication plug-ins

This adds the needed functions the eurephia framework requires to
retrieve a list of all configured plug-ins - eDBget_plugins().  And
it includes eDBauth_GetAuthMethod() which is used to lookup what
kind of authentication method a specific user account/certificate
combination should use.  If the authentication backend requires
a different username for this, that can also be configured in
this user account/certification setup.
