Enable travis-buddy on GitHub repos

[jayvdb]

https://github.com/bluzi/travis-buddy provides a synopsis of the travis error on the pull request

https://travisbuddy.com

[jayvdb]

I would suggest the following order

1. https://github.com/coala/documentation
2. https://github.com/coala/cEPs
3. https://github.com/coala/corobo
4. https://github.com/coala/coala-vs-code
5. https://github.com/coala/projects
6. https://github.com/coala/coala-html
7. https://github.com/coala/community
8. https://github.com/coala/coala-bears

And after each we check that it is working as expected before continuing to the next.

There should be individual issues opened for this in the corresponding repos or just this issue should be referenced in the individual PRs?

[jayvdb]

No need, just use Related to https://github.com/coala/meta/issues/114

[palash25]

Can this issue have multiple assignee? I think we can complete it much faster if we divide individual repos amongst ourselves. If you don't mind @manankalra .

cc @jayvdb

[jayvdb]

Please read the issue again @palash25 .

Another option is to enable travieso

maybe we try that after travis-buddy, if we dont like travis-buddy.

c.f. coala/coala#4891

[manankalra]

travis isn't set up for cEPs; needed?

[jayvdb]

coala/documentation#555 (comment) - a buddy error. looks nice!

travis isn't set up for cEPs; needed?

ok, skip that one for now.

For corobo:
As per my knowledge, travis-ci/travis-ci#5121 isn't solved yet. Also, the docs do not mention anything of this sort - https://docs.travis-ci.com/user/notifications/#Configuring-webhook-notifications.

Will have to omit on_success: never for now.
