Using the TinyMCE Javascript/HTML WYSIWYG editor in PicoLisp applications

1. Install the 'tinymce' package

   $ apt-get install tinymce

2. In the application's runtime directory, create a link to the tinymce
   installation, e.g.:

   $ ln -s /usr/share/tinymce/www tinymce

3. In your application, 'allow' the tinymce installation directory:

   (allowed ("myApp/" "tinymce/")
      ... )

4. On each page where you want to use tinymce in textareas, insert two calls to
   'javascript' somewhere at the beginning, but before the first textarea,
   e.g.:

   (action
      (html 0 "Title" "lib.css" NIL
         (javascript "tinymce/tiny_mce.js")  # Insert two lines
         (javascript "lib/tinymce.js")
         (form NIL
            ...
            (gui '(+BlobField) '(txt : home obj) 60 8 "Memo")  # Use textareas

5. Normally, you would use an application-specific configuration. In that
   case, copy "lib/tinymce.js" to "myApp/tinymce.js", modify the plugins,
   buttons etc, and use (javascript "myApp/tinymce.js") in your code.
