Allow SSH keys to be of type ECDSA (rather than only RSA and DSA)

[AlexT]

RFC 5656 defines elliptic-curve (ECDSA) key formats (host and user) for use with SSH-2, and associated ECDH key exchange methods. OpenSSH has supported these since 5.7. Most government agencies (USA, Russia, France, et al) have already switched from RSA/DSA to ECDSA.

SecureCRT does not currently support these ("Unknown file format"). That's unfortunate since it prevents users from exclusively switching to the more secure key format.
