Enables key view loop autorecalculation in the BrowserWindow.

Enables key view loop autorecalculation in the BrowserWindow on Mac.  This fixes a bug where you would cycle through a background tab's links even after selecting a different tab.

The specific nib change is to check "Auto Recalculates View Loop" for the "Browser" window.

TEST=Open Chromium.  Open a new tab.  Press tab and verify that we are correctly cycling through the links in the new tab.

The word "tab" is completely overloaded, so let me know if the CL description
makes no sense.

I won't be able to submit this tonight (headed out soonish), so I'll take the
extra time to play around with autocalculation and see if that helps us.

Experimentation showed that we weren't autorecalculating, and most votes seem to
be in favor of turning that option on.  New patch attached.  A smaller one,
even.

Seems to work. LGTM.

This changes the flags from 0x20000000 to 0x20000030. Next time, can you comment
on the meaning (e.g. "I checked the FooBar property on the containing view")?
