Bugfix for the issue #109: Fails to properly parse NOSE_COVER_PACKAGE environment variable.
Now the following line works correctly:

os.environ['NOSE_COVER_PACKAGE'] = 'package1,package2,package3'
Suppress tracebacks caused by ConfigErrors.

Show a kind error message instead of a traceback
when an unknown configuration variable is found in
a file.
Add the ability to skip byte-compiling the sources.
Use `nose.__loader__` to load 'usage.txt', if available.

Previously we only used `nose.__loader__` if we thought
that the loader was zipimporter. Additionally, we use
`nose.__file__` to build the path to 'usage.txt' as
suggested by PEP-302.
Start fixing some import failures with python 3
Fix: missing method on test class from another module raises Error
Issue #535: fix nose.importer to work when the same modules are reachable from different paths along sys.path, due to e.g. symlinks.
(note: not sure this will work under Windows, this may need further tweaking)
Fix tests under py32 by creating the symlink dynamically (it didn't get copied into build/tests).
Also, try to make things work under Windows (but untested).
Replace abspath() with realpath(), and remove redundant call to normpath()

Fix formatFailure expection if missing tb in exc_info

The FailureDetail plugin should not fail in formatFailure if no
traceback is in the exc_info tupple ('err' parameter). This happens,
e.g. when used with testtools:
