Fix #181: generate default gitlab ci config

[stanislas-m]

Still one question remaining:

My problem is the way the database.yml is generated:

test:
  dialect: postgres
  database: buffalo-test_test
  user: postgres
  password: postgres
  host: 127.0.0.1

Since the PostgreSQL server is not on 127.0.0.1 in this case (it will be on a dynamic host created by Gitlab), the test will fail. So, we can either:

• ask the user to change the host by hand
• let Buffalo customize it by tweaking Pop
• change Pop template to use envOr helper on test case (so we can provide env in the ci script)
• tweak it at build time, with a bash command like sed or awk

In my opinion, the third option is the best and would not break legacy setups.

"change Pop template to use envOr helper on test case (so we can provide env in the ci script)" 👍

@markbates It should work now. I've added a case without Pop too.

LGTM. :) Thanks!
