Add CI support for build test and auto deploy

[snowme34]

Attempt to add travis-ci

Will find a way to auto deploy, either pull from docker hub (travis ci push the image), or use webhook to trigger the server to pull, rebuild, restart.

Travis ci deploy

Travis ci deploy script

We might want to only run the test for pull requests
