This is a lot simpler from a concurrency perspective. Training values
can get committed to the database immediately, rather than in
long-running flat file batches.

Just like the actual chain data structure, this value is now loaded
lazily, since it's stored in the filesystem.

This allows markov to save (hopefully) in parallel using a
ProcessPoolExecutor. Since objects are sent over-the-wire and copied,
pruning in parallel is not an issue.

This moves the self.__touch() call around in markov's Chain class such
that it will only access truly available data.

* Chain.__touch() is a new function that updates the last time a markov
chain was accessed
* Fix a bug that would not reliably update the last access time of the
chain during Chain.add()

Markov chains used to prune the chains themselves from memory, but now
that behavior is specifically delegated up the chain to the Bot
structure instead.

* .items() call required when loading a markov chain into memory
* `who.nick` instead of `who~ for get_chain call

This will just send a message to the user who just updated their markov
reply chance with the final value it was set to, so there are no
surprises.

Whenever someone says something, there's a chance that markov will
interject his opinion. Users can also set the chance between 0.0 and the
default value (in the config) if they want to see markov replies less
often.

If something is changed in a markov chain it gets flagged as dirty,
which is used to determine whether the chain should be saved.

If you don't use/access your chain every N seconds (300 by default), it
will unload your chain from memory and save it to disk.
