Add --incremental to our docker-compose.yml

[jbubar]

Overview

Docker takes 30 or more s to reload after saving changes. This is quite a pain, especially when working with css.
@akibrhast told me about the --incremental tag, which speed up the reload time by at least 3 times!
I messaged @cnk about this and she said it would be fine.
