Title: Mark App::pluginPath as deprecated and don't use it anymore.

It was already just a BC wrapper:

public static function pluginPath($plugin) {
return CakePlugin::path($plugin);
}

So there is no need to go through that still.
Directly using CakePlugin::path makes most sense.
Added a note that it is deprecated and that the new method should be used from here on forward.
