py3: use stdlib's parseaddr() to get sender header in notify extension
In Python 3, email headers are unicode string so using
stringutil.email() will not work as it compares with bytestring. So
let's use email.utils.parseaddr() from the stdlib which has a consistent
behavior across Python versions. The same is done in patchbomb
extension already.

// Enforcing
"eqeqeq" : true, // true: Require triple equals (===) for comparison
"forin" : true, // true: Require filtering for..in loops with obj.hasOwnProperty()
"freeze" : true, // true: prohibits overwriting prototypes of native objects such as Array, Date etc.
"nonbsp" : true, // true: Prohibit "non-breaking whitespace" characters.
"undef" : true, // true: Require all non-global variables to be declared (prevents global leaks)
// Environments
