50g: Create directory-like GROB for custom menus

[Joe Horn]

Alternative if you don't mind using the SYSEVAL command: Put the desired string (1 to 5 characters long) on level 1 of the stack, then do this:

#2E1EBh SYSEVAL

That creates a menu-style label grob containing the desired label. If you also want the grob to be expressed as a string (as Matteo's program does), just follow the above with →STR.
