[Bf-python] Blender.sys.basename() different from os.path.basename() on Windows

[Levi Schooley]

Hello,

I know this is a bit picky, but I just noticed that the following script prints
two different results.

# On Windows only
import Blender, os
print os.path.basename("foo/foo.py") # prints "foo.py"
print Blender.sys.basename("foo/foo.py") # prints "foo/foo.py" ???

Is this expected behaviour? It's not a big problem since Blender comes bundled
with the os module, but it would be a little more convenient if Blender.sys
worked "as expected." Blender.sys.dirname() has the same issue.

Thanks!
Levi
