Summary: email.Parser.Parser doesn't check for valid Content-Type

Initial Comment:
See the attached traceback illustrating how to
reproduce the
problem.  A sample triggering message is also attached.

The problem is that the Content-Type is 'multipour
alternative', 
but the Content-Type field has a valid 'boundary='
parameter. 
The parser doesn't check that Content-Type is valid; it
just creates
sub-Message objects for each part it finds that is
separated by the 
boundary.  Then, when Generator goes to check
Content-Type, it
discovers that the content-type *is* invalid and it
returns 
'text/plain' instead! Generator tries to _handle_text
and instead
 finds the list of sub-Message objects.  BOOM!
