2017-11-08	jenkins.rs: Add `result_from_job`	Teddy Wing
	This method will take a job JSON payload returned from the Jenkins API (http://jenkins/job/:project/:id/api/json), and return its status, success, failed, or pending. A new `JobStatus` type represents the status of jobs.
2017-11-07	jenkins.rs: Add `get_jobs`, test HTTP request	Teddy Wing
	Try making our first HTTP request to the Jenkins API. Use Basic authentication with our name and access token. The 'reqwest' format is based on https://doc.rust-lang.org/stable/std/string/struct.String.html Eventually this method should return a `Vec` of jobs, actually job URLs, but at least we know it works and gives us a 200.

2017-11-07	Add modules for GitHub and Jenkins interaction	Teddy Wing
