2017-11-07	pull_request.rs: Idea to get needed data from JSON payload	Teddy Wing
	Non-working app code, but the test tries to check that we get a structure with the right data given a JSON payload coming from the GitHub PushEvent webhook (copied from https://developer.github.com/v3/activity/events/types/#pushevent).
2017-11-07	Add modules for GitHub and Jenkins interaction	Teddy Wing
	Empty stub modules that will be filled in with the communication code.
2017-11-07	main.rs: Add web server and "hello world" route	Teddy Wing
	Basic web server and dummy response using 'rouille'.
2017-11-07	Add 'rouille' crate	Teddy Wing
	A neat web micro-framework. Seems small and lightweight, nice macro syntax. Upgraded to Rust 1.21.0 at the same time, as it or its dependencies wouldn't compile on 1.16.0.
2017-11-07	Initial commit. Cargo init.	Teddy Wing
	Initialised new project with: $ cargo init --bin kipper Rust 1.16.0. (I know, it's super old, but that's what I have on my machine right now without going out to get the latest version.)
