This allows to add an ECC key and to set the capabilities of an ECDSA
key.

Fix printing of the ECC algorithm when creating a signature.

2011-02-03 Werner Koch <wk@g10code.com>
* sign.c (do_sign): Use openpgp_pk_algo_name.
* keygen.c (ask_algo): Show ECC algos only in expert mode. Add
non-combined menu entries for ECDSA and ECDH.
(ask_key_flags): Use openpgp_pk_algo_name.
2011-02-03 Werner Koch <wk@g10code.com>
Finished ECC integration.
