Summary: Better token-related error messages

Initial Comment:
There were some complaints recently on c.l.py about the rather 
non-informative error messages emitted as a result of the tokenizer 
detecting a problem.  In many situations it simply returns 
E_TOKEN which generates a fairly benign, but often unhelpful 
"invalid token" message.

This patch adds several new E_* macrosto Includes/errorcode.h, 
returns them from the appropriate places in Parser/tokenizer.c and 
generates more specific messages in Python/pythonrun.c.  I think the 
error messages are always better, though in some situations they may 
still not be strictly correct.

Assigning to Jeremy since he's the compiler wiz.

Skip
