Add all rules to the HTMLHint.defaultRuleset (but set non-enabled ones to false)

[pdehaan]

Is your feature request related to a problem? Please describe.
Just started playing w/ this library today and this caused a bit of confusion (although admittedly I'm probably not using the library in the recommended way; API).

console.log(JSON.stringify(HTMLHint.defaultRuleset, null, 2));

Gives me the following output:

{
  "attr-lowercase": true,
  "attr-no-duplication": true,
  "attr-value-double-quotes": true,
  "doctype-first": true,
  "id-unique": true,
  "spec-char-escape": true,
  "src-not-empty": true,
  "tag-pair": true,
  "tagname-lowercase": true,
  "title-require": true
}

Not all rules seem to be documented, and I was looking for a stricter set of rules so there was some trial and error. I ended up coming up w/ this solution which seems a bit, sketchy:

const DISABLED_RULES = [
  "attr-sorted",
  "attr-value-not-empty",
  "attr-value-single-quotes",
  "attr-whitespace",
  "empty-tag-not-self-closed",
  "head-script-disabled",
  "href-abs-or-rel",
  "script-disabled",
  "space-tab-mixed-disabled",
  "tag-self-close",
  "tags-check",
];

const allRules = Object.keys(HTMLHint.rules).sort().reduce((obj={}, name="") => {
  obj[name] = !DISABLED_RULES.includes(name);
  return obj;
}, {});

OUTPUT

{
  "alt-require": true,
  "attr-lowercase": true,
  "attr-no-duplication": true,
  "attr-no-unnecessary-whitespace": true,
  "attr-sorted": false,
  "attr-unsafe-chars": true,
  "attr-value-double-quotes": true,
  "attr-value-not-empty": false,
  "attr-value-single-quotes": false,
  "attr-whitespace": false,
  "doctype-first": true,
  "doctype-html5": true,
  "empty-tag-not-self-closed": false,
  "head-script-disabled": false,
  "href-abs-or-rel": false,
  "html-lang-require": true,
  "id-class-ad-disabled": true,
  "id-class-value": true,
  "id-unique": true,
  "inline-script-disabled": true,
  "inline-style-disabled": true,
  "input-requires-label": true,
  "script-disabled": false,
  "space-tab-mixed-disabled": false,
  "spec-char-escape": true,
  "src-not-empty": true,
  "style-disabled": true,
  "tag-pair": true,
  "tag-self-close": false,
  "tagname-lowercase": true,
  "tagname-specialchars": true,
  "tags-check": false,
  "title-require": true
}

Describe the solution you'd like
Should the HTMLHint.defaultRuleset property return ALL properties and only set true for the enabled default properties but include all the rest of the properties set to false? Wouldn't change the default behavior, but might make it easier for people to save the defaultRuleset value to a config file and change 1-2 values instead of having to build the .htmlhintrc config file manually.

Describe alternatives you've considered
See above, but I ended up just scraping ALL the rules and then selectively turning conflicting/unwanted rules off.

const DISABLED_RULES = [
  "attr-sorted",
  "attr-value-not-empty",
  "attr-value-single-quotes",
  "attr-whitespace",
  "empty-tag-not-self-closed",
  "head-script-disabled",
  "href-abs-or-rel",
  "script-disabled",
  "space-tab-mixed-disabled",
  "tag-self-close",
  "tags-check",
];

const allRules = Object.keys(HTMLHint.rules)
  .sort()
  .reduce((obj={}, name="") => {
    obj[name] = !DISABLED_RULES.includes(name);
    return obj;
  }, {});
