chore(deploy): travis deploy

Due to an issue with the conditional deploy `tags` option, a `deploy/tags.sh` is used to determine if the build is a tag and if it is the latest tag.

Deploys to s3 if a tag's tests pass on travis `/integrations/goangular/<tag>/`.
If the tag is the latest tag it will also deploy to `/integrations/goangular/latest/`.
