why can't this just be: value="{{prefs.homepage.value}}" and remove homepage_?

[dschuyler, 2015/09/17 18:02:41]

We can do that :)  This next patch uses prefs.homepage.value
directly.  Now edits are done immediately.
So there's no more need for a 'submit this change' button (since
changes happen directly).

Done.

Also, there's a DCHECK about the url being valid that I'd
need to look into further.  Since the url is being interactively
created, it may be temporarily invalid while editing.
