#5 Extract Channel Logging Feature to Plugin

[Rob Yurkowski]

At the time of writing, pyGBot is capable of keeping logs for its own actions, as well as a log of channel actions/text. In recognition of the fact that the latter is:
a) not actually part of the core operation of pygbot (i.e. it can be removed without any significant impairment of operational condition, as opposed to its system log, which is chiefly used to diagnose problems)
b) likely to be largely in demand as a feature, but bloat in minimal-weight operation of the bot
c) incapable at the moment of logging more than one channel -- an absolute 'must' if the functionality is to be useful in the slightest

... be it resolved that the channel logging feature be extracted to an enabled-by-default plugin, and that it be enhanced to offer poly-channel logging.

Additionally, this feature could be used to log #pygbot and make logs available online.
