mailpipe: flesh out reponse text for invalid messages and signing errors.
This may be a user's first exposure to PGP, so it's a bad idea to be
cryptic ;).

mailpipe: convert to pgp-mime's new Signature verification.
This brings us up to date with the following pgp-mime commit:

Author: W. Trevor King <wking@tremily.us>
Date: Thu Sep 20 10:12:38 2012 -0400
signature: add Signature class for more Pythonic verification.
Now verify_bytes() returns a list of `Signature`s instead of XML.
This should be much easier for callers to handle, and it provides a
layer of insulation between the gpgme-tool output and Python code.

mailpipe: skip `.gitignore` files in Maildir mailboxes.
I use empty `.gitignore` files so Git will create the
`test/mail-in/new` and `test/mail-in/tmp` directories on checkout, but
the Maildir mailbox thinks they are messages. Since the files are
*not* messages, skip them when constucting the Maildir message list.
I don't foresee any side effects from this (it's an odd filename for
real Maildir delivery), but I log the skipped filenames just in case.

mailpipe: flesh out InvalidMessage attributes before raising exceptions.
This tacks on all the interesting attribute data which the function

mailpipe: fix InvalidHandlerMessage error message construction.
`target` is an explicit argument, not in `**kwargs`.
I also removed the InvalidHandlerMessage error logging, because we're
raising an exception. The calling function can log the exception if
it catches it. If it doesn't, the user will see the message in the
traceback.

mailpipe: replace `respond` callback with exceptions.
Now mailpipe sub-functions will raise Response or InvalidMessage when
they want to respond to the incoming email. This takes advantage of
Python's exception handling to avoid passing the `respond` callback
all over the place. It also allows us consolidate error message
construction in `_get_error_response`, which will lead to both simpler
program logic and more consistent response messages.
Other changes to make this cleaner:
* Renamed functions in pygrader.email:
_construct_email -> construct_email
construct_email -> construct_text_email
* Pulled _get_assignment out of submission.run.
