README.md, example, and Travis cleanup

Remove the IRC notifications from Travis (we're not using IRC anymore), and the
stable/experimental badge from README.md (because they aren't being kept up to
date).

While there, updated both the README and the example to not use the now-obsolete
`.enableWakeup` method.
