Docker-caching-and-better-slack-notifications (#102)

* test docker caching and slack

* try this

* this _might_ do it

* cleanup

* just realized this is running on self-hosted, so github cache doesn't make sense

* fix logging noise

* cache npm modules during test

* fiskerBot and icon

* quotes (just in case)
