*	Extract lint scopes from `cargo watch`	Ryan Cumming	2019-06-26	1	-4/+5
\| \| \| \| \| \| \| \| \| \| \|	Currently all of our VS Code diagnostics are given the source of `rustc`. However, if you have something like `cargo-watch.command` set to `clippy` it will also watch for Clippy lints. The `rustc` source is a bit misleading in that case. Fortunately, Rust's tool lints (RFC 2103) line up perfectly with VS Code's concept of `source`. This checks for lints scoped to a given tool and then splits them in to a `source` and tool-specific `code`.
*	Initial Visual Studio Code unit tests	Ryan Cumming	2019-06-26	1	-0/+161
	As promised in #1439 this is an initial attempt at unit testing the VSCode extension. There are two separate parts to this: getting the test framework working and unit testing the code in #1439. The test framework nearly intact from the VSCode extension generator. The main thing missing was `test/index.ts` which acts as an entry point for Mocha. This was simply copied back in. I also needed to open the test VSCode instance inside a workspace as our file URI generation depends on a workspace being open. There are two ways to run the test framework: 1. Opening the extension's source in VSCode, pressing F5 and selecting the "Extensions Test" debug target. 2. Closing all copies of VSCode and running `npm test`. This is started from the command line but actually opens a temporary VSCode window to host the tests. This doesn't attempt to wire this up to CI. That requires running a headless X11 server which is a bit daunting. I'll assess the difficulty of that in a follow-up branch. This PR is at least helpful for local development without having to induce errors on a Rust project. For the actual tests this uses snapshots of `rustc` output from a real Rust project captured from the command line. Except for extracting the `message` object and reformatting they're copied verbatim into fixture JSON files. Only four different types of diagnostics are tested but they represent the main combinations of code actions and related information possible. They can be considered the happy path tests; as we encounter corner-cases we can introduce new tests fixtures.
