'id-length' is invalid

[ariporad]

Hi,

I cloned this repo and (installed the dependencies, and) ran npm run lint, and I'm getting this error:

/Users/Ari/Developer/airbnb-js-style/packages/eslint-config-airbnb/node_modules/eslint/lib/config.js:141
throw e;
^

Error: eslint-config-airbnb:
Configuration for rule "id-length" is invalid:
Value "data["1"].properties" has additional properties.

I'm not sure what's causing it. I've just spend the past hour debugging it.

Looks like we need to bump eslint up to at least 1.3.0 - the version in which the "properties" option was added to id-length. (https://github.com/airbnb/javascript/blob/master/packages/eslint-config-airbnb/package.json#L31)

For now, npm install eslint@1.3.x should fix it for you locally.

I'll send pr when I get home in a few hours 

Thanks!
