allow option of errors being transmitted over http

IE8 has restriction on cross domain requests where the protocol
must match. Therefore if hosting off of http it would be unable to
submit errors. This will allow specifying that we use a relative
protocol for IE to allow IE8 errors being served over http to be
submitted
added docs for the new setting
bump version numbers
