* 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.

Every time a user sends a message, there is now a chance that markov
will reply with a random message based on what they said. !markov chance
allows lookups and setting of the chance that a user may receive a
message.

* Markov allchain is generated from all markov chains in the save
directory for the given channel. This omits starting processes for
known markov chains.

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 each have their own process keeping it updated and
synchronized. The markov plugin has been upgraded to account for this.

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

* Plugins all derive from Omnibot.Plugin. There still is a base plugin,
in case we want to have another plugin backend instead of a GenServer
* All plugins are monitored by a unique Plugin.Supervisor, which is in
turn started by the PluginSupervisor (yes this is confusing, yes it
needs to be renamed)
* Any other auxiliary child processes may be started through the
Plugin.children/1 function.
* By default, plugins have a CfgState process which is an Agent that
keeps track of the plugin's configuration and state
* Plugin API is now called through the GenServer backend for better
synchronicity.
* Very few changes to the front-facing Plugin API, which is nice

* using Plugin.GenServer now uses Plugin.Base so that is not required
* Remove Omnibot.Plugin because all it did was include Plugin.GenServer
and Plugin.Base

Both markov and wordbot have some auxiliary processes that run to keep
track of things. Previously, they both had custom supervisors grafted on
to the Plugin.Base - now, this grafting is automated with
Plugin.Supervisor.

* 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.
