Set up continuous integration for salt proc

[katyhuff]

Consider circleci or travis. (it doesn't seem to be git-hooked into PRs)

Will do it closer to SaltProc v1.0 Release

[katyhuff]

Please set up ASAP.

@katyhuff Looks like I do not have permissions on arfc/saltproc to set up CI.
This is weird because I made this repo, and I have owner permissions for any repo I created.
But not for saltproc.

Could you please use your super-access to check it out?
