Summary: Removed eval() from csv

Initial Comment:
The eval() step in the csv module can be eliminated, 
resulting in better security, more clarity, and a little 
speed.

The idea is to make successive attempts to coerce 
the string to a python type:
   int(s), long(s), float(s), etc.

This allows the logic to be controlled precisely and for 
specific types to be included or excluded (unicode 
types for instance).

The patch is attached and passes all regression 
tests.  It should also work fine under Py2.2.
