- Fixed a bug where configuration instances provided to plugins were using the wrong expression engine.
- Changed Plugin.getHelp() to return a list of strings for sending to the channel instead of a single string. Most plugins will return a singleton list.
- Compound plugins can now recursively generate their help strings so that all commands are visible in the help document.
- Modified PluginManager to show all commands registered for a plugin instead of just the top-level ones.
