[webkit-dev] EWS now parses error logs in case of build failure

These enhancements are great. There is one feature of the old EWS that I
really miss, which is that I used to get emails when some EWS failed. With
new EWS, I have to keep checking back the bugzilla to see if any of them
have failed periodically.

Can we add a feature to opt into such an email notification? Maybe a flag
on a patch or JSON configuration file somewhere.
