New language level: module. It behaves like `require'ing the
  definitions window, except that the REPL will contain
  every defined identifier in the module, not just those
  that are provided.

TeachPacks are back.

THINGS STILL MISSING (and promised to be broken)

 - launchers
 - project manager

FUNCTIONALITY CHANGES
- TeachPacks are now implemented as modules.
  They are `namespace-require'd when execute is clicked.

- the get-teachpack-names method is gone from
  the language<%> interface.

- the expand-program method is now called after
  expansion is finished, with eof. This is a good
  time to kill the eventspace that was created
  for the expansion.

MINOR CHANGES AND BUG FIXES

- moved the Windows menu to the 
  second to last position of the menubar.

- split/collapse are now in the show menu

- check syntax now works properly behind 
  define-syntax, and other misc. bugs fixed.

new drscheme, tools and framework manuals released. the drscheme manual
is still quite rough.
