* Move m_key member of Effect into Plugin * Pass key to Instrument ctors and instantiaters * Add pluginKeys to all plugin selector widgets, and let them pass the keys when instantiating the instruments; or, if the keys must be passed over threads, pass the keys to the Engine using `Engine::setDndPluginKey()` * As instrument plugin libraries now also need to get their key passed, their second argument, which was always the same as the first, is now used to pass the sub plugin keys. This affects *all* instrument plugins. * Plugin.h: Add more virtuals to `SubPluginFeatures` in order to draw logos and images into instrument selector widgets * LadspaSubPluginFeatures: Implement the `displayName` virtual because the new behaviour to resolve displayNames is to first look at the SubPluginFeatures, which, without override, returns the superior plugin's name (Plugin.cpp) Additional: * PluginFactory.h: Allow setting up search paths without discovering plugins yet * Plugin.h: Add full documentation (should be checked)
