[Partially done] Add pr-opened label to issues when a pr is opened that fixes/refs the issue

[hzoo]

why: to make it easy to see which issues already have someone working on them

• maybe even signal the relevant pr somehow (if active, active x days ago)

name could be different just a suggestion

Parse

1. just the "fixed tickets" line in our pr template
2. anything that looks and smells like github ID # and is an issue
3. (1 || 2) + title of the ticket

Item 1 in the list above is done, but I'm hitting a super weird issue where the sha for the webhook (what we use for the auth) doesn't match what I'm getting for the payload + secret. Haven't had this problem with any other type of events.

@DrewML Ihad a similar issue sometime ago. IDK if it helps: http://stackoverflow.com/questions/30269030/github-push-event-signature-dont-match

[DrewML]

@marcoslhc you rock - thank you! That's probably the issue. Going to give it a shot tonight.

Done in a36ba80 already? I already saw it in action lol

[DrewML]

@hzoo Yeah, I had temporarily disabled signature validation and forgot to re-enable it, lol. Going to put in the fix @marcoslhc recommended now.

Done so far:
