Removed the 'crypto' dependency

[3bl3gamer]

The crypto module brings a huge amount of code to the browser build and it's removal reduces the build size by 400 KiB or by 25%.

The crypto.randomBytes Generates cryptographically strong pseudorandom data. That strength is not needed since these hex strings are used only as ids/classes in the generated HTML.

This change may cause test fails for some users, but this can be fixed by stubbing Math.random.

Another option would be to generate sequential IDs:

let lastId = -1
export default function genStringId() {
  lastId += 1
  return lastId+''
}

This won't cause problems with tests but may reveal the amount of e-mails generated by some application (if used on the server side).
