Updated to reflect WG status.  Also made the following changes:

1. Reduced new algorithms list to just one (ECDSA P=256).

2. Included revised definition of key:value pairs for DKIM keys and 
signatures.  One thing I thought about: should the “k=“ in keys to 
be mandatory now that RSA isn’t the only algorithm?  Or leave the 
default as is, so that anyone using ECDSA must use the “k=“ tag to 
signal its use?

3. Just noticed that the format is mess up for the ABNF notation - dang. 
  Will fix that.
