These are two other cases where grouping is not really necessary. For accessibility, the checkbox at the end of the download interstitial dialog does not need to be in the same group as the radio button, and the question text can more simply just label the radiogroup. The vbox is still necessary to hide the section, but is not related to accessibility or dialog structure.

Move all of the overlay pieces into an include file except for the
DTD's that could not be put there. Inline the DTD's into the files
where they were used. Update comments in macWindow.inc.xul and browser.xul
to more accurately reflect the current state.

The overlay defined two elements (helpMenu, menu_ToolsPopup) for all
platforms and three others (windowMenu, baseMenuCommandSet, baseMenuKeyset)
that were MacOS only. The two all platform elements and windowMenu were only
used once and inlined into browser-menubar.inc. The rest of the MacOS only
elements were conditionally inlined into browser-sets.inc.
