Subject: Remove the authenticateWithDSA method

This has been deprecated for quite a while and using DSA should be
discouraged.

-	 * After a successful connect, one has to authenticate oneself. This method
-	 * is based on DSA (it uses DSA to sign a challenge sent by the server).
-	 * <p>
-	 * If the authentication phase is complete, <code>true</code> will be
-	 * returned. If the server does not accept the request (or if further
-	 * authentication steps are needed), <code>false</code> is returned and
-	 * one can retry either by using this or any other authentication method
-	 * (use the <code>getRemainingAuthMethods</code> method to get a list of
-	 * the remaining possible methods).
-	 * 
-	 * @param user
-	 *            A <code>String</code> holding the username.
-	 * @param pem
-	 *            A <code>String</code> containing the DSA private key of the
-	 *            user in OpenSSH key format (PEM, you can't miss the
-	 *            "-----BEGIN DSA PRIVATE KEY-----" tag). The string may contain
-	 *            linefeeds.
-	 * @param password
-	 *            If the PEM string is 3DES encrypted ("DES-EDE3-CBC"), then you
-	 *            must specify the password. Otherwise, this argument will be
-	 *            ignored and can be set to <code>null</code>.
-	 * 
-	 * @return whether the connection is now authenticated.
-	 * @throws IOException
-	 * 
-	 * @deprecated You should use one of the
-	 *             {@link #authenticateWithPublicKey(String, File, String) authenticateWithPublicKey()}
-	 *             methods, this method is just a wrapper for it and will
