Added email notifications when comments are added to an owners projects.  Struggled getting ENV variables into  my development.rb, ended up having to explicitly call the ENV file into the initializer BEFORE the app was initialized.  Working with gmail and smtp at the moment, will need to add vars to heroku for this to work.  Also tried to clean up controller logic while I was in there.
Updated comment notification mailer to have both html & text version.  This is working in a few mail clients that I've tested, mainly gmail, yahoo & mac mail.  Unsure how actionmailer is determining which version to send out or if it's sending out both but rails guide seems to imply that both are.  Also updated testing for the mailer to be a bit less brittle.
