creation of a "client identity" (in form of a client certificate)

I was actually working on this for the next beta :-) ie. automatic creation and use of SSL client certificate file on startup if one does not exist. It will be created using RSA,sha256,2048 bit and C=US,O=Personal,CN=localhost. There will also be two new $sslcertsha1 and $sslcertsha256 identifiers that return the fingerprint of the currently loaded SSL client certificate file for use with /nickserv cert add.
