Any optimizations here are an exercise to the reader. For example, this installs SBT using package managers for simplicity and low maintenance, but manual methods could dramatically reduce build times. Fingers crossed for appveyor/ci/issues/3361 to get built-in Scala support one of these days. 😉

For my needs, skip_branch_with_pr: true was necessary to stop duplicate jobs for open pull-requests and their respective branches.
