#118 relative from ... import fails

[John Belmonte]

Givin this module structure:

mypackage
|-- __init__.py
`-- subpackage
|-- __init__.py
|-- foo.py
`-- bar.py

File foo.py does a relative "from ... import":

from bar import xxx

causing pychecker 0.8.12 to fail as follows:

Processing mypackage.subpackage.foo
ImportError: No module named bar

I have tested this with Python 2.1, 2.2, 2.3 and 2.4. I was
able to reproduce the problem.

Note that this problem does *not* occur when executing:

pychecker mypackage/subpackage/foo.py

It only happens when executing:

pychecker mypackage.subpackage.foo
