[Mac] Add a preference for the tab key cycling between just form fields, or links as well.

[Mac] Add a preference for the tab key cycling between just form fields, or links as well.

XIB change:
Add a checkbox bound to FilesOwner.tabsToLinks underneath the translate webpages
preference.

BUG=31177
TEST=Uncheck Chromium-->Preferences-->Under the Hood-->Pressing Tab... Then press Tab on Google.com and the links don't get focus; it alternates between search field and location bar.

i think we're currently only making nib changes on 10.5 to avoid the situation
we got into a while back. I assume you're making this from 10.6?

Pink: I (well, Mark) re-saved the XIB on 10.5.
