This also removes the 't' flag from 'guioptions'.

Side effect: :term[inal] -> :te[rminal]

Closes #3003.

-GTK+ and Motif support Tear-off menus.  These are sort of sticky menus or

-6.3 Tearoff Menus
-
-The Win32 GUI emulates Motif's tear-off menus.  At the top of each menu you
-will see a small graphic "rip here" sign.  Selecting it will cause a floating
-window to be created with the same menu entries on it.  The floating menu can
-then be accessed just as if it was the original (including sub-menus), but
-without having to go to the menu bar each time.
-This is most useful if you find yourself using a command buried in a sub-menu
-over and over again.
-The tearoff menus can be positioned where you like, and always stay just above
-the Main Vim window.  You can get rid of them by closing them as usual; they
-also of course close when you exit Vim.

-							*:tearoff* *:te*
-:te[aroff] {name}	Tear-off the menu {name}.  The menu named must have at
-			least one subentry, but need not appear on the
-			menu-bar (see |win32-hidden-menus|).
-
-Example: >
-	:tearoff File
-will make the "File" menu (if there is one) appear as a tearoff menu. >
-
-	:amenu ]Toolbar.Make	:make<CR>
-	:tearoff ]Toolbar
-This creates a floating menu that doesn't exist on the main menu-bar.

-Note that a menu that starts with ']' will not be displayed.
