Lessen verbosity of "Exit" menutag items to appear more consistent across
menus from one module to the next.

Replacing "Exit this menu (returning to previous)" with "Exit this menu".

Shift Console->Saver menu items to place the default item at the top, making
this menu consistent with Console->Repeat, Console->Font, Console->Screenmap
and many others which place the default choice at the top.

NOTE: SVN r249751 changed things so that these menus highlight the active
selection, so the idea that the default choice (now at top) "can be selected
immediately by hitting ENTER" is not possible unless the default choice is
the currently active setting (e.g., on first visit to the menu). However, it
is still warranted to have the default choice at the top of the menu.
