* No longer runs e2e tests inside of Saucelabs because Chrome is also installed on Travis CI and we should keep Saucelabs available for other browsers that don't run inside of Dockers or Travis.
Scopes the logic, that skips the build if only Markdown files, only to PR builds. This avoids issues where we merge in a lot of PRs to master, followed by a docs PR which ends up silencing potential build errors.
* No longer just skips the unit test and e2e tasks if only markdown files changed. Now everything will be skipped, since there is nothing that tests against the `.md` files.
* Prints messages for the deploy tasks that run inside of Pull Requests but end up in a NOOP.
Currently every deployment runs in a single Travis job concurrently. This messes up the logs and it's also hard to see what actually runs at all.
The different deployment jobs should run concurrently in the deploy build stage.
