PSF core grant, day 8

Today was one of those big, single document days. I wrote a guide on how triagers should triage. This is for people who have gotten the Developer role on the issue tracker and need to know how to properly file issues away.

Otherwise the usual typo fixes occurred. I even got help from Antoine Pitrou who did some commits on his own! I'm glad that other core developers are starting to feel comfortable about editing the docs as they have been made purposefully accessible to core devs so that I never become a bottleneck, just the initial author.
