Summary

Add Pull Request to the Subversion commit template

[emaste]

I would put it before Differential Revision: to help cement the idea that D-R should go last (even though you'd generally not have both of these on the same commit) and because Differential Revision: is too long and pushes the rest of the text over to the right.

switch order of "Pull Request" and "Differential Revision"

At @mat's request, I'm also making a change to the svnadmin area. However, I can't upload that part to phabricator, because phabricator diffs are anchored to /head instead of /. But here's what it looks like:

Index: svnadmin/hooks/scripts/log-police.py

Note that before using this, it would be much better to finally have the pull request -> PR gateway working.
