Feature request: Changing attestation type

[Mik13]

Attestation type should be changeable, because "direct" (the only possibility currently) is not always wanted and/or needed.

Maybe we can allow indirect and none too (for this, the none format must be implemented too).

Example here: Mik13@0896449

I would say that this is fixed but currently when I try it I still tend to get a 'direct' attestation even if I explicitly ask for 'none'. Closing this and opened separate issue for the bug at #30.
