Contexture

+++++++++++++++++++
- Fix objects() iterator

+++++++++++++++++++
- configure() now takes parameters in addition to URL string.

+++++++++++++++++++
- A new ``format`` argument for Context._update(). When ``False`` it will not attempt to process curly braces by calling .format() on the message string.

+++++++++++++++++++
- Add non-logging based configuration (context.configure()), to get around logger hijacking (I'm looking at you, celery)
- Context processor can now wait for the handler queue to empty, automatically. This simplifies things for short-running process and guarantees EOL message delivery.

+++++++++++++++++

- Keep messages until channel is open
- monitor: add queue declare args

``lcmon``:

- ``--keys``: will now stay in order
- Add ``--trim``
- Add ``-z``
- Add version to help
- Add tests

+++++++++++++++++

- Add missing config.conf to MANIFEST.in
- Deal with variable args in AMQP callbacks
