* 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 Signed-off-by: Alek Ratzloff <alekratz@gmail.com>
