Title: Fixed crash when ignore wasn't specified.

Small bugfix; I didn't specify `ignore` when testing my last patch and it was throwing this error:

```
~/js/uncss/lib/lib.js:100
if (ignore.indexOf(selector) !== -1) {
^
TypeError: Cannot call method 'indexOf' of undefined

```

This makes it so you can ignore the `ignore` option. :-)
