Remove autoloading from Plugin::load()
Remove autoloading from Plugin::load()

Plugins should be autoloaded independently of Plugin::load(). This
method now is responsible for exposing a plugin to the rest of the
framework/application. Loading a plugin does the following:

* Exposes it in the default routes.
* Exposes the CLI tools it may provide.
* Allows assets to be served by the dispatcher filter.
