Additional email options

1. Added 2 options for email: encryption and domain. Both were needed for my set up to work.
2. Removed the validation of the to_email because the way it was, you can't send email to multiple recipients. Without it, you have set the string to '[email protected],[email protected]' and it will send the email to both. I think it would be nicer if it was an array of string as you could then do validation but I couldn't figure out how to loop through an array in Puppet and I ran out of time for this.

Would you be able to take care of spec tests? I don't think removing the validations is the way to go, adding the comma to the regex seems to make more sense. Until puppet 4.0 (or parser = future) we won't be able to validate elements in an array so I've left stuff like that off until that becomes more adopted.

spec tests: yeah, I really ought to get set up with that. Let me get myself set up, need to be able to start doing tests. I just started with Puppet and was mostly checking it out and making a proof of concept but at think at this point I'm settled on it so it's worth taking the time.

email list: good point, validating for the comma make more sense.
