Split plugin location and loading out of the initializer and into a new Plugin namespace, which includes Plugin::Locater and Plugin::Loader. The loader class that is used can be customized using the config.plugin_loader option. Those monkey patching the plugin loading subsystem take note, the internals changing here will likely break your modifications. The good news is that it should be substantially easier to hook into the plugin locating and loading process now. [Marcel Molina Jr.]
