* 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

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.
