Support outlawing /// <reference> style imports.

The reasoning is that these are superseded by ES6 style imports, and the syntax
overall isn't too pleasant.

node.referencedFiles only refers to <reference path= statements, which is good

I like this rule too! This theme of rules that encourages using modern-TS is a good use-case for TSLint in my opinion.

Couple notes: TS is adding a <reference types=...> directive. We might want to allow that - I haven't read enough into its use case yet to say for certain though. There's also <reference no-default-lib="true"/> which we also probably want to allow (and your code does).

With all that in mind, I think we should change the name of this rule slightly, perhaps to no-reference-path or no-path-reference or something similar?

[jkillian]

src/tsconfig.json should also have a similar change, running grunt should automatically update both files.

[mprobst]

Done.

What about making this no-reference, and then adding disallow-types if it becomes a thing? It makes sense to me to make anything that's reference related in one option, as much as that's possible.

So "no-reference": true for now, and then later if we need to support it "no-reference": [true, "disallow-types"].

[jkillian]

👍 Agreed, keeping it as no-reference seems fine, and various options (either negative or positive) can be added as needed later.

[mprobst]

Cool. I think this is good to go then, unless I'm missing something.

[jkillian]

Agreed - thanks for the PR!
