mac: Window buttons should keep "active" view when bubbles / tabpose are open on 10.7

mac: Window buttons should keep "active" view when bubbles / tabpose are open on 10.7

This matches the behavior of NSPopover.

This is done by overriding the SPI _sharesParentKeyState, which works on 10.7 but
not on 10.6. If we want to get this right on 10.6, we could use the SPI described
in http://code.google.com/p/chromium/issues/detail?id=44087#c42 , but since we
didn't feel we need this until now, we can probably live with this being 10.7-only.

I do need this functionality for the history-swipe-overlay.

BUG=none
TEST=Click e.g. bookmark star. Bookmark bubble should appear, browser window close
button should still look active.
