Setting up travis testing
Bump Hatchet Dependency

- Hatchet now raises an error on failure, must flag `allow_failure: true` if you expect a failure on builds.
- Hatchet no longer masks `Anvil::Builder::BuildError` exceptions
- Hatchet::App#push! for both Git and Anvil now returns just an output string. On failures an exception will be raised
Hatchet knows how to set itself up on Travis CI

Run `bundle exec rake hatchet:setup_travis` instead of manually running each command
Auto Retry deploy failures 3 times on travis

When a deploy fails hatchet will now retry a deploy HATCHET_RETRIES times before raising an error. This mitigates ghosts in the machine and makes the test suite's red/green status more truthy.
