Fixed collector 2057: Testing.makequest broke getPhysicalPath()

when used on anything other than an app object.
Also added an 'environ' argument if you want to use something
other than os.environ, and added a couple trivial tweaks from 
ZopeTestCase.makereqeust.
Added unit tests for this stuff.

+You can optionally pass stdout to be used by the response,
+and an environ mapping to be used in the request.
+Defaults are sys.stdout and os.environ.
+
+If you don't want to start a zope app in your test, you can wrap other
+objects, but they must support acquisition and you should only wrap
+your root object.
