Added the `ILightingScenesDynamic` interface to add an event for devices that support retrieving scene data from the lighting system at runtime. Also added the `sortOrder` property for the `LightingScene` type to allow for control over the sort order of scenes on the UI
In order to solve some dependency issues that keep cropping up, MC

on startup. This will allow for all plugins that use the MC Messengers
library to use the same version without fear of overwriting a dll due to
loading of plugin libraries.
