Release 2008.04.26

From this point on, I'm going to try to do a release at the end of any week that sees improvements to the Retro codebase.

This week brings a couple of minor changes and improvements:

• Ngaro JS now included in the package
• A tool (in Toka) to build an image.js for Ngaro JS
  (This does not work properly on 64-bit systems, I'll try to fix in the next week or two)
  
• A new (remap-keys) hook has been added to allow alteration of the values returned by key before they can be processed by other words
• New whitespace module, which uses (remap-keys) to convert TAB, CR, and LF to SPACE
• retro.config renamed to extensions
  
• Minor cleanups to start organizing the modules
  

My short term plans are to finish organizing the module sources, and to put up an online tool for building a custom forth.image without requiring anything other than a web browser.
