plugin.yml and permissions lookup

prior to reading, mind that plugin.yml is not the only method to add permissions. Bukkit also supports runtime modifications of its permissions list via code. If you see a permission ingame that isn't defined by plugin.yml, you might find it defined in code at plugin enable to accommodate variables like the world names or biome names provided by the server.

RTP only defines permissions and provides them to the server. Tabcompletion for permissions is provided by permissions plugins.

Few commands are provided to the server, since RTP provides its own command and tabcompletion system beyond the command /rtp (it was quite a lot of work to build from scratch and refine, so tell me you like it if you get a chance)
