More Python work

Over the weekend I worked on various Python bugs.

• Describe the errors="surrogateescape" encoding parameter.
• Fixed a memory leak in curses.panel, though Serhiy Storchaka noted that the resulting bugfix can be used to trigger a segfault. I posted a possible fix for review.

I should probably just commit my edits to the Unicode howto at this point, and then move on to updating the regex howto.

New bitofpython.com web site

Last Friday I finally remembered to write Steve and correct my error in supplying the wrong IP address. After he changed it, that meant the new bitofpython.com web site is up. The site is a static one, built using the Pelican site generator. No new podcast episodes, though; I still have secret hopes of reviving it, but I never seem to get around to writing an episode or setting up an interview.
