docker-crystal spec

docker-crystal build

In place of using (or even requiring) a locally installed version, it will spin up an ephemeral container. The version used is (in order of priority) CRYSTAL_VERSION env var, the crystal version in shard.yml, or latest. Any build artifacts or docs generated will appear in the local file system as though they had been built natively.
