Can we hide the buttons besides disabling?

chrome://files is only for debugging purpose. I think just disabling the buttons
is enough. Adding more code is not good.

Sorry, I didn't check carefully before, but this change broke Files.app.
chrome.app.window.contentWindow seem to be always undefined.
