Single post in Wonder Trading [WIP]

Hi guys! It is now possible to set up Wonder Trading. To do this, go to the Wonder Trade section of the Trade Centre, select the Pokémon you want to put up, and go! For now, this will just put your Pokémon up for Wonder Trading. The actual trade will not complete until I have added more code. However, I can't test without some Pokémon in there, so that's why I'm opening this much up now, okay? Wonder Trades should now work properly! Let me know if they don't :p Have fun!
