Replace tslint.json with tslint.js or tslint.yaml

I don't like config formats which don't support comments, and although tslint supports comments in the configuration file tslint.json, it's not strictly JSON and so github highlights comments in all red. So I'd like to use another option.

Option 1, JavaScript: tslint.js:

module.exports = {
    "defaultSeverity": "error",
    "extends": [
        "tslint:recommended"
    ],
    "jsRules": {},
    "rules": {
        "no-any": true,
        // TODO perhaps we *should* use the 'I' prefix?
        "interface-name": [true, "never-prefix"],
        "no-unused-expression": [true, "allow-fast-null-checks"]
    },
    "rulesDirectory": []
}

Or option 2, YAML: tslint.yaml:

defaultSeverity: error
extends:
    - 'tslint:recommended'
jsRules:
rules:
    no-any: true
    # TODO perhaps we *should* use the 'I' prefix?
    interface-name: [true, never-prefix]
    no-unused-expression: [true, allow-fast-null-checks]
rulesDirectory: []

I prefer option 2, but I know YAML can be a bit of an adjustment, so let me know what you think, @BANG88 .

EDIT: yaml uses # for comments, not //

I've created #13 and #14 to cover both options.

@seanf I think we should keep using tslint.json. as far as i know I don't write any comments in the tslint.json file. because the rules are not difficult to understand. so do not use .js or yaml file. its not standard as me.

@seanf if you are have some time would you mind add more comments for index.ts since the coding style is not so important for index.ts because we have tslint yet. 😄

@BANG88 it's not really about whether the rules are difficult to understand, but being able to explain the reasons for choosing certain rules. But it's not a big deal.

Not sure I follow you.
