portable fortune program

[J.Jacob]

Here is the GUI version.  It has menu options for a new fortune and
for copying to the system clipboard.  The whole thing is 104 lines of
source code.

Usage:
Put fw.py and your 'allfortunes' file somewhere in your sys.path.  The
format of the allfortunes file should be like the variable called
modulequotes in fw.py; modulequotes is used if it cannot find the
allfortunes file.
Now do:
python -c "import fw; fw.run()"

It should be portable and backwards compatible to python version
1.5.2, please let me know if it does not work with your python
installation.

I like work ... I can sit and watch it for hours.
