Doc removes localStorage items, that it doesn't own.

This is done by Docs.LocalStore#cleanup. I usually run docs from http://localhost or file://localhost, and items set by other applicantions are removed. I would like the Docs app to not require dedicated domain.

Thanks for pointing out. Hadn't really considered the localhost case.

Anyway, I think it's time to remove this old cleanup routine. The JSDuck versions that introduced these localstorage keys should be long gone by now.
