    Copyright notice (where it was included) had the wrong URL for LICENSE.
    Fix that and shorten text around it.  Add to files that didn't have it.

new file:   experiments/bottle/LICENSE
new file:   experiments/bottle/__init__.py
renamed:    experiments/bottle.py -> experiments/bottle/bottle.py
    Put bottle in its own directory so it can have its own LICENSE file.
    (Note: LICENSE didn't appear as such in the downloaded .tar.gz file
    but the text was on the bottlepy.org web page itself.)
