* calendar.py: remove stuff now built in time; some cleanup and
generalization in the calendar printing
* cmd.py: use __init__.
* tzparse.py: This module is no longer necessary -- use builtin time instead!
* sndhdr.py: renamed to whatsound.py; use new aifc module for AIFF/AIFC
* ftplib.py: added close() (closes without sending QUIT command)
* aifc.py: documented close()
* Several modules: change "class C(): ..." to "class C: ...".
* flp.py: support for frozen forms.
* Added string.find() which is like index but returns -1 if not found
