Add AppVeyor pull request previews

Merges manubot/rootstock#262
References manubot/rootstock#198

Add an AppVeyor continuous integration file to enable manuscript build previews in pull requests.
AppVeyorBot comments in pull requests with a link to the latest manuscript PDF.
Move shared continuous integration steps to an install script.
Change the continuous integration skip message in the deploy script to work across multiple continuous integration services.

 If updating `master` via a pull request, proceed to push the commit to GitHub and open a pull request.
 Once the pull request is ready to merge, use GitHub's "Create a merge commit" option rather than "Squash and merge" or "Rebase and merge" to preserve the rootstock commit hashes.

+# Previewing pull request builds with AppVeyor
+
+You can optionally enable AppVeyor continuous integration to view pull request builds.
+Unlike Travis CI, AppVeyor supports storing manuscripts generated during pull request builds as artifacts.
+These can be previewed to facilitate pull request review and ensure formatting and reference changes render as expected.
+When a pull request build runs successfully, **@AppVeyorBot** will comment on the pull request with a download link to the manuscript PDF.
+
+To enable AppVeyor, follow steps 1 and 2 of the [AppVeyor welcome](https://www.appveyor.com/docs/) to sign in to AppVeyor and add your manuscript repository as an AppVeyor project.
+The repository already contains an `.appveyor.yml` build configuration file, so no other setup is required.
+AppVeyor only runs when it detects changes that are likely to affect the manuscript.
