Mtj.jibber

----------------

- Provide Affilate Command base class which can serve as the base for
providing moderation/role handling features
- Use Affiliate class to provide a RandomPromotion class which does what
the name suggests.
- Added some more mock values to the test client in debug mode.

----------------

- Fully require the ``bot`` argument for all methods.
- Support hooking up handlers to lower level events, making it possible
to hook that up via the config file to available module/class paths.
This is implemented in the ``presence`` module.
- For the mean time ``Presence`` is the new base ``Handler`` for the
lower level events.
- First such handler is the automatic rejoin when bot is no longer in
a channel, implemented in the ``Muc`` class.
- Another one is greeter, implemented in the ``MucGreeter`` class.
- The ``Command`` class is now a subclass of ``Handler``; that is now
the class that will be checked. In the future this requirement may
be dropped once validation of argument signature for the provided
callables can be done.
- A ``LastActivity`` feature; can be used as a ``!seen`` trigger to
get back a rough idea on when the user was last seen. This intends to
be a demo implementation.
- Test client class now supports scheduling properly; clear method now
works as intended.
- Other minor cleanup and updated tests.

----------------

- ``MucChatBot.send_message`` now much more resistant to malformed
messages generated by package method, and now allow overriding of both
``mbody`` and ``mhtml`` arguments which will cascade down to the real
``send_message`` method, if bot authors want complete output control.
- Consistently handle lists that may be generated by package_methods in
the same way as a single text or dict.
- No longer will assign a reference to ``bot`` for every instances of
``Command`` class.

----------------

- Private chat message handling for private message commands.
- Core configuration file generation from the jibber shell command.
- Helper method for dynamic module reloading within debug mode.

----------------

- Core functions implemented, including connect to XMPP server as a muc
client, and to provide trigger handlers and dynamic module/object
loaders so those triggers can make something happen.

--------------------

- Added some useful bots classes.
