6edd258608 Fix a problem with @contextmanager not detecting a broken generator 
that yields after a throw().  Make @contextmanager not reraise
exceptions, but return a false value in that case instead.  Add test
cases for both behaviors.

a9f068726f Fix a bug in nested() - if one of the sub-context-managers swallows the 
exception, it should not be propagated up.  With unit tests.

1a5e21e033 Updates to the with-statement: 
- New semantics for __exit__() -- it must re-raise the exception
  if type is not None; the with-statement itself doesn't do this.
  (See the updated PEP for motivation.)

- Added context managers to:
  - file
  - thread.LockType
  - threading.{Lock,RLock,Condition,Semaphore,BoundedSemaphore}
  - decimal.Context

- Added contextlib.py, which defines @contextmanager, nested(), closing().

- Unit tests all around; bot no docs yet.
