Moved 'peak.util.WSGIServer' to 'wsgiref.simple_server'.

Update peak.util.WSGIServer to latest WSGI version, ditching the old
IRerunnableCGI interface that it used.  Add a new subclass to
'wsgiref.handlers', suitable for HTTP/1.0 origin servers like WSGIServer.

Port all of PEAK's internal and example apps from IRerunnableCGI to
IWSGIApplication, and add a new 'WSGI' command wrapper that lets you run
non-PEAK WSGI applications in PEAK's containers.  For the time being, we're
keeping IRerunnableCGI around, however, because it's a more natural
interface for the CGI/FastCGI containers to use.  See CHANGES.txt for more
details on these issues.  Also, fixed an issue with templates outputting
Unicode instead of ASCII (which is all they really support at the moment.)

'SCRIPT_NAME' should be empty at site root.

Fix incorrect handling of numeric-only statuses.

Python 2.3, for no apparent reason, changed the behavior of BaseHTTPServer
with respect to send_response()'s interpretation of 'code'.  Fixed
'WSGIServer' for compatibility.  (Problem reported by Wayne Larsen and Jon
Watts.)

Added 'peak serve' and 'peak launch' commands, for running "CGI" apps in
a browser from the local machine.  For example, doing this::

  PYTHONPATH=examples/trivial_cgi peak launch import:the_cgi.DemoCGI

from the base directory of a PEAK CVS checkout or source distribution will
launch the 'trivial_cgi' demo program in a new or current browser window.
Any application runnable with 'peak CGI' should also be runnable with
'peak serve' or 'peak launch', which makes it very useful for running
local browser-based apps or testing an application without CGI or FastCGI
available.  The modules that support this new functionality are
'peak.util.WSGIServer' (which implements a web server based on Python's
'BaseHTTPServer', that can run 'running.IRerunnableCGI' objects) and
'peak.tools.local_server' (which provides PEAK integration.)
