Possible issue with selector '#.identifier'

[tmpfs]

When an id selector contains a period I get a runtime error here:

https://github.com/fb55/css-what/blob/master/index.js#L97

Such as (truncated for brevity):

TypeError: Cannot read property '0' of null
    at getName (/home/muji/git/makestatic/compiler/packages/auto-title/node_modules/css-what/index.js:97:36)
    at parseSelector (/home/muji/git/makestatic/compiler/packages/auto-title/node_modules/css-what/index.js:145:13)

    at Function.select [as selectOne] (/home/muji/git/makestatic/compiler/packages/auto-title/node_modules/css-select/index.js:20:51)
...

As browsers handle this fine I am wondering whether it is legal to have a period in an id as far as selectors go.

Can you advise? If you feel it's worth patching I am happy to give it a shot and submit a PR.

This is definitely a bug, for now escaping the period should fix this.
