Summary: decimal.py signal/exception fix

Initial Comment:
Traps should be set on signals, not conditions. 
decimal.Signals in the implementation is actually
listing conditions.

The attached patch brings the implementation into line
with the spec & PEP 327.  decimal.Signals is changed to
list signals, not conditions. Context._raise_error is
modified to handle signals properly.

19 tests fail in test_decimal.py, but I'm not sure how
to fix it.

It's a start.  The docs would also need changes to explain
the difference between signals and conditions, and how to
enable traps.

A boolean "signal" attribute on exceptions may help.  Set
DecimalException.signal to False, set .signal on individual
signal exceptions to True, and .signal on InvalidOperation
subclasses to False.
