core: sets plugin_path to loaded plugins
While loading a plugin in the manager using #load_botmodule_file this will remember the directory of the file that is being loaded in @next_plugin_path. In the plugin/BotModule initialization we set the path in plugin_path of the plugin. This was the only solution I could find to get this information in the plugin. It is useful because this allows the plugin to know in which directory it is located, it can then easily access data files stored alongside the plugin. Some built-in plugins (see #42) use the data/rbot/templates to copy data files on bot load (see #repopulate_botclass_directory) into the profile directory (~/.rbot/).
