Done.

you can hardcode the host here (perhaps a new url constants file is in order for
WebUIs in components).

[cjhopman, 2013/09/12 00:41:00]

We also know that url.host() == host here, we could just use that.

[nyquist, 2013/09/12 17:42:12]

Removed the host argument, but kept the URL for now since the plan is to use it
for chrome://dom-distiller/entry/SOME_ID. Is that OK?

args should be aligned horizontally

Done.
