[Haskell] Sifflet visual programming language, release 0.1.6

[gdweber at iue.edu]

Sifflet 0.1.6 is now available on Hackage.

New in this release:
*   Sifflet offers to save your work if you give the quit or open file
    command and have unsaved changes.
*   Sifflet now builds with Gtk2hs 0.11.
*   Some bug fixes and improved error checking.

Sifflet is a visual, functional programming language. 
Sifflet programmers define functions by drawing diagrams.
Sifflet shows how a function call is evaluated on the diagram.
It is intended as an aid for learning about recursion.

*   A picture explains Sifflet better than words:
    please see the screenshot showing how to evaluate 3!:

*   Features:
    -   Visual editor.
    -   Visual tracer/debugger which shows how recursive and
        other function calls, expanding the computation when the
        student requests it, to support active learning.
    -   A tutorial with 31 pictures and about as many pages.
    -   Number, string, and list data types.
    -   Palette with a small number of primitive functions.
    -   Runnable examples of compound functions.
