[orm-devel] A couple clean up items in 0,7

[Mike Watkins]

Found a couple more things:
-----------------------------
in orm/datasource.py:

add
from orm.errors import *  # or at least import IlligalPrimaryKey - see next

-----------------------------
in orm/errors.py
consider renaming
IlligalPrimaryKey to IllegalPrimaryKey # and also in orm/datasource.py and 
in orm/orm.txt

----------
in orm\adapters\psql/datasource.py

add
from orm.errors import *  # (only one referenced but may as well)

line 67, add sys to import (referenced in this file)
import string, sys

----------
Consider normalizing the import statements. In some newer files this is 
done already.
i.e. change

from debug import debug
from relationships import relationship

to

from orm.debug import debug
from orm.relationships import relationship

to avoid on conflicts in the future.

Just a few early morning thoughts.
Cheers,
Mike
