   512: menu keybindings should change automatically according to pref

  FUNCTIONALITY CHANGES

   - The teaching languages in DrScheme only have the primitives
     that are listed in the documentation, now.

   - DrScheme now prints exact real numbers as graphical fractions
     (instead of the (+ 1 1/2) notation). These are also valid as
     input, but you have to copy and paste to get them into your
     program.

   - Added an "insert fraction" menu item to the edit menu for
     inserting fractions directly into the program.

  MINOR CHANGES AND BUG FIXES

   - check syntax now rechecks the syntax right after an
     alpha conversion, since alpha conversion may introduce
     syntax errors into the program. Also, this makes it easier
     to rename multiple identifiers.
