Webware for Python

In HTTPResponse.recordSession() I changed:

	self.setCookie('_SID_', sess.identifier())

to:
	cookie = Cookie('_SID_', sess.identifier())
	cookie.setPath('/')
	self.addCookie(cookie)

Currently, sessions are created on demand. That means the user may have 
already browsed into the subdirectories of a site when the session id is 
first recorded in a cookie. I guess by default, cookies are associated with 
the URI of the request (say http://localhost/a/b/c/) and only work for that 
URI or ones underneath it.


Also, I added this to Application's config settings:

	'Debug':	{
		'Sessions': 0,
	}

If you turn that on you get debugging output. We can expand this with other 
items. Typical usage looks like:

	debug = self.setting('Debug')['Sessions']
	if debug: prefix = '>> [session] isSessionIdProblematic:'
	...
	if debug: print prefix, 'session expired:', sid
