* Markov.Chain.add_weight/4 would return a fresh new markov chain,
instead of using all of the previous values of the chain that was
being modified. This would result in resetting the reply_chance value
to the default of 0.01.
* Add tests to make sure this doesn't happen to add_weights in the
future.

merge/1 takes a nonempty list of markov chains to merge
merge/2 takes two markov chains of the same order and sums their weights

* Markov chains will train and generate chains correctly now
* Implement Markov.save_chains/0
* Add a couple more utils that help accomplish the above

* Markov chains record words correctly from a single line to the end of
their line with a couple of exceptions.
* Start working on using ETS for storing markov chains, and saving it as
a DETS periodically

* train/2 takes a chain and a list of words to train them on
* add_weight/4 takes a chain, a list of words (the key), the word it
points to, and an optional increment which will increment the value of
a weight, or insert the weight.

For some reason there doesn't appear to be a binary search function in
Elixir's standard library, so this implements that.

Wordbot is a little more complex of a bot module and I've been working
on it here.
Other than wordbot module, a few minor tweaks have been added all around
that don't really affect anything.
