Needs to become a localizable resource.

(Also below);

[grt (UTC plus 2), 2012/10/25 14:46:53]

Is this ever built for branding=Chromium?

[huangs, 2012/10/29 21:15:16]

This has not been built for Chromium.

[huangs, 2012/10/29 21:15:16]

Will make this localizable once we create shortcuts.  Moot for this CL.

[grt (UTC plus 2), 2012/10/30 13:02:55]

Is it possible to put in a safeguard so that it never will be built for
Chromium?

[erikwright (departed), 2012/10/30 14:20:39]

We don't do anything to prevent it, but there are a lot of steps between where
we are today and making this useful in Chromium.

[erikwright (departed), 2012/10/30 14:20:39]

I spoke with grt, as long as the strings are internationalized (i.e., defined
separately and appropriately for Chrome and Chromium builds), it's not an issue.

If these strings are only required for the shortcuts CL, please remove them from
this one.

If they are required for the Add/Remove registration, please do the
internationalization.
