2974	Appveyor does redundant builds for PRs	exarkun	GitHub <noreply@…>	"Once a PR has been opened, Appveyor builds both the branch and the branch merged into master.  Building the branch at this stage is not terribly useful.  Also, Appveyor is slow and has deep queues, so these extra builds noticably delay the development process.

Turn off branch builds when a PR exists.
