Nosegae

- Worked around SDK 1.2.5's way of aggressively adding logging handlers (25).
Note that this still allows Nose to capture and report your app's log messages.
Thanks to Jason H. Smith for the bug report and patch.

- Added support for Google App Engine SDK 1.1.9 (18). Thanks to Mahmoud Arram
and hackerblinks for patches.
- Fixed a path issue that causes ImportError on Windows (19). Thanks to kveretennicov
for the patch.
- There is a more informative error now if tests run with something lower than
Python 2.5 (14).

- Fixed bug in handling of modules shared between sandboxed and
non-sandboxed code that caused sys.modules to be empty in sandbox
(among other problems). Thanks to Kumar McMillan for the bug report
(2).
- Changed sys.path munging to ensure that libs that may be in google
and system libraries are loaded from google's libdir. Thanks to
Kumar McMillan for the bug report and patch (6).
- Fixed bug in how the sandbox shared module set was maintained between
entries into the sandbox, which could cause a cascade of import errors
under certain arrangments of test and app code. Thanks to Kumar McMillan
for the bug report (7).

- Updated datastore handling to use a nosegae-specific datastore by
default. This prevents the test run from clearing the default
dev_appserver datastore, as would happen with earlier
releases. Thanks to Andy for raising the issue.

- Updated self-test to use trestle so that the resulting documentation
is more clear for end users.
